How this is calculated

Oven recipe: 400 °F for 25 min.
In °F: 200 °C × 9/5 + 32 = 392 °F.
400 °F − 25 °F = 375 °F.
Rounded to the nearest 5 °F: 375 °F.
Whole cuts, ham and poultry never go below 325 °F (FoodSafety.gov).
Nothing goes above your air fryer’s 400 °F.
25 × 3/4 = 18.75: the window opens at 18 min. 25 × 4/5 = 20: it closes at 20 min.
Shake or flip at half the long end: 20 ÷ 2 = 10 min.
In °C: 375 °F is 190.6 °C, shown as 190 °C.

Temperatures are rounded to the nearest 5 degrees in the unit you picked, then held to the roast floor and your air fryer’s max. The window’s short end rounds down and its long end up, to whole minutes.

Don’t overfill the basket: USDA says it cooks unevenly and can leave food undercooked, so cook a big load in batches. The time starts when the food goes in; Ninja recommends a 3-min preheat.

Oven to air fryer conversion calculator. Air fryer temperature, time window and the safe internal temperature for your food.

This oven to air fryer conversion calculator turns a recipe's oven temperature and time into an air fryer setting and a time window to start checking. It keeps the setting within your air fryer's top heat and shows the USDA minimum internal temperature a food thermometer must read before the food you picked is done.

Oven to air fryer conversion: the 25 °F rule, and what the calculator adds to it

To convert an oven recipe to an air fryer, set the air fryer 25 °F lower and plan on 75 to 80 percent of the oven time. Ninja, Cosori and Whirlpool each publish the 25 °F drop; Cosori and Whirlpool cut the time by 20 percent, and Instant's UK conversion chart by 20 to 25 percent. A chicken recipe that roasts at 400 °F for 25 minutes becomes 375 °F (190 °C) for 18–20 minutes.

USDA's Food Safety and Inspection Service (FSIS) describes air fryers as essentially countertop convection ovens, and gives 5 to 25 minutes at 350 to 400 °F as the general range for air-fried foods. The makers present their rule as an approximation: Cosori's recipe book calls its 25 °F and 20 percent an average whose results may vary, and Whirlpool notes that every model varies. The calculator gives the time as a window that spans the makers' figures, with the first check at its short end.

On top of the makers' rule, the calculator applies these adjustments:

Rounding to 5 degrees. The setting is rounded to the nearest 5 degrees in the unit you use, °F or °C, and the rounding comes before the floor and the cap below.
The 325 °F roasting floor. FoodSafety.gov says to set the oven to 325 °F (163 °C) or higher when roasting meat and poultry, and the calculator holds chicken, turkey, steaks, chops, roasts and ham to the same minimum in the air fryer. That roasting page leaves out foods containing ground meat and poultry, meatloaf and sausage included, so ground meat keeps its converted setting.
Your air fryer's top setting. The result never goes above the top you choose: 390 °F (the Philips Viva HD9220), 400 °F (the Ninja AF100 and AF140 and the Cosori Lite, and the default) or 450 °F (the Air Fry preset of Cosori's air fryer oven).
Convection recipes. A recipe written for a convection (fan) oven keeps its temperature. LG's convection modes take 25 °F (14 °C) off automatically, and Whirlpool says air fryers and convection ovens may use similar temperatures, so only the time shortens, to 80–100 percent.
Frozen packaged food. Air fryer directions on the package come first, as FSIS advises. With oven directions only, the window opens at half the oven time, after Instant's advice to cut frozen food's time by around 50 percent.
Raw stuffed breaded chicken. FSIS says not to cook raw, stuffed, breaded chicken breast products in an air fryer and to follow the manufacturer's cooking instructions, so the calculator gives no air fryer setting for them.

The third result card, "Done when the center reads", shows the USDA minimum internal temperature for the food you pick, with the spot to measure or the cue to look for: 165 °F (74 °C) for chicken, turkey, leftovers and casseroles; 160 °F (71 °C) for ground meat and egg dishes; 145 °F (63 °C) for fish and shellfish, and for steaks, chops and roasts followed by a 3-minute rest. FSIS's air fryer page says cooking times differ with the size and power of the appliance while the safe internal temperature stays the same. Use the time to plan the first check, and take the food out when the thermometer reads that minimum.

Choose "Air fryer to oven" to run the same rule backward: 25 °F hotter, with the time divided by 0.80 and 0.75. For a °F or °C reading outside a recipe, use the temperature converter; for cups, grams and spoons in the same recipe, the cooking converter.

How to convert a recipe with the calculator, using chicken at 400 °F

The calculator opens on chicken roasted at 400 °F for 25 minutes in a regular oven, converted for an air fryer whose top setting is 400 °F. Replace the numbers with the ones your recipe prints.

1. Leave the toggle at the top on "Oven to air fryer". "Air fryer to oven" runs the conversion the other way.

2. Type the recipe's temperature in "Oven temperature" and pick °F or °C beside it. Each unit keeps its own number, so switching from 400 °F to °C shows the °C field's own value (200 when the page opens), with no conversion: type what the recipe prints, in the unit it prints it.

3. Enter the time in "Oven time", in minutes. A recipe that says 1 hr 15 min goes in as 75.

4. Pick the food in "What you’re cooking". It decides the safe-temperature card, whether the 325 °F floor applies, and whether the time card tells you to shake or flip. Five of the fourteen options show a hint underneath, such as "Frittata, quiche, egg bites" for egg dishes.

5. Open "Your oven and air fryer" if the recipe was written for a convection (fan) oven or your air fryer's top setting is 390 °F or 450 °F. The block stays folded, and its summary line, "Your oven and air fryer: regular, 400 °F max", shows what is set without opening it.

6. Read the three cards. For the opening recipe they say 375 °F (190 °C); 18–20 min, with "Shake or flip at 10 min · check at 18 min"; and "Done when the center reads" 165 °F (74 °C), measured at the innermost thigh and wing and the thickest part of the breast.

7. Cook to the reading. Set 375 °F, flip the chicken at 10 minutes, and at 18 minutes push a food thermometer into the thickest part. At 165 °F it is done; below that, give it a few more minutes and measure again.

Under the cards, a line reminds you that the result is "A starting point, not a doneness guarantee" and names the makers behind the rule. Two tables, "Oven temperatures, converted" and "Oven times, converted", list seven common settings for the food you chose, with your row highlighted when it is one of them; a tag marks any row held at the roast floor or at your max. The USDA table lists all ten rows of the FSIS chart, with °C from FoodSafety.gov and your food's row picked out, and "How this is calculated" folds open to the arithmetic for your numbers.

Eight oven recipes converted for the air fryer

A 430 °F recipe on an air fryer that stops at 400 °F

"Something else" at 430 °F for 30 minutes, with the top setting left at 400 °F. Taking 25 °F off gives 405 °F, 5 °F more than the air fryer can reach, so the temperature card reads 400 °F (205 °C) and a line under the cards says: "Your air fryer tops out at 400 °F; the recipe converts to 405 °F. Set the max and expect the long end of the time or more." The time card shows 22–24 min, with a shake or flip at 12 min and the first check at 22. With no meat, fish or eggs picked, the third card reads "No USDA minimum" and asks "Meat, fish or eggs? Pick it above".

With an air fryer that reaches 450 °F, such as an oven-style model, choose that top setting instead. A 450 °F oven recipe for 20 minutes then converts to 425 °F (220 °C) for 15–16 min, and no cap line appears.

Chicken and ground beef from the same 325 °F, one-hour recipe

Chicken or turkey at 325 °F for 60 minutes would convert to 300 °F, below the 325 °F that FoodSafety.gov gives as the lowest oven setting for roasting meat and poultry. The card reads 325 °F (165 °C) instead, and a line explains: "Raised to 325 °F: FoodSafety.gov says to roast meat and poultry at 325 °F (163 °C) or higher." The window is 45–48 min, with a flip at 24 min, and the third card asks for 165 °F (74 °C).

Switch the food to "Ground meat or sausage" and the setting drops to 300 °F (150 °C) with no line, because FoodSafety.gov's roasting page leaves out foods containing ground meat and poultry. The window stays 45–48 min, and the card changes to 160 °F (71 °C), with the note that ground meat "can brown before it is safe". Both start checking at 45 minutes: the floor changes the temperature, and the window comes from the oven time alone.

A convection recipe at 425 °F for 20 minutes

Chicken from a recipe written for a convection oven, with "Recipe is for a convection (fan) oven" switched on inside "Your oven and air fryer"; the summary line changes to "Your oven and air fryer: convection, 400 °F max". LG's convection modes run 25 °F below a regular bake, so the recipe has already taken its cut and the calculator starts from 425 °F as written. A 400 °F air fryer caps that: the card reads 400 °F (205 °C), and the capped line says the recipe converts to 425 °F. The window is 16–20 min, 80 to 100 percent of the oven time, with a flip at 10 min and the first check at 16.

Frozen nuggets with oven-only directions: 425 °F for 20 minutes

"Frozen packaged food" at 425 °F for 20 minutes. The setting follows the usual rule, 400 °F (205 °C), and the window opens early: 10–16 min, with a shake at 8 min and the first check at 10. A line under the cards reads "Package prints air fryer directions? Use them (USDA). Instant halves the oven time for frozen food, so the window opens at half." Instant's guide keeps the oven temperature for frozen food; the calculator keeps the 25 °F drop and uses Instant's 50 percent as the start of the window.

The third card reads "See the package", since frozen products range from fully cooked to raw. If the label says raw or uncooked, the target is 165 °F (74 °C) for poultry and 160 °F (71 °C) for ground meat.

A pork roast at 350 °F for 90 minutes, past the 60-minute timer

"Steaks, chops or roasts" at 350 °F for 90 minutes. The setting is 325 °F (165 °C), which lands on the roasting floor without needing a raise, so no floor line appears. The window is 1 hr 7 min – 1 hr 12 min, with a flip at 36 min. The long end passes an hour, so a line adds: "Over an hour: the Ninja AF100 and AF140 and the Cosori Lite stop the Air Fry timer at 60 min. Restart it, or use Roast if yours runs longer." On the Ninja AF100, the Roast timer runs up to 4 hours.

The third card reads 145 °F + 3 min rest (63 °C), with "rest it before carving or eating (USDA)". Take the roast out when the thermometer reads 145 °F, then let it stand 3 minutes before slicing.

Salmon fillets at 400 °F for 15 minutes

"Fish and shellfish" at 400 °F for 15 minutes gives 375 °F (190 °C) for 11–12 min, with a flip at 6 min and the first check at 11. The window matches Instant's UK chart, which turns 15 oven minutes into 11–12 in the air fryer.

The third card reads 145 °F (63 °C), "or opaque and flaking; shrimp pearly and opaque". FoodSafety.gov pairs the number with a visual test: fish is done when the flesh is no longer translucent and separates easily with a fork, and shrimp, lobster, crab and scallops when the flesh turns pearly or white and opaque.

Potatoes at 425 °F for 40 minutes: a result equal to the top setting

"Vegetables and potatoes" at 425 °F for 40 minutes converts to 400 °F (205 °C), the same as the default top setting. A result that matches the maximum counts as within reach, so no cap line appears, and the window is the plain 30–32 min, with a shake at 16 min and the first check at 30. Vegetables carry no 325 °F floor either: at 300 °F in the oven they would convert to 275 °F.

The third card reads "No USDA minimum" with "Cook to the recipe’s cue": the fork-tender center or the browning the recipe describes.

Frozen chicken Kiev or cordon bleu

"Stuffed breaded chicken" covers raw products such as chicken Kiev or cordon bleu. Choose it and both result cards turn red: "Don’t air fry these", sourced to USDA FSIS, and "Oven only", with "Follow the package’s oven time". The conversion tables and the arithmetic fold disappear, and the line under the cards reads: "USDA FSIS: don’t cook raw, stuffed, breaded chicken in an air fryer; follow the package’s cooking instructions." The third card still shows 165 °F (74 °C), filling included, the temperature FSIS sets for the center of any stuffing.

In the air fryer to oven direction the same food converts normally, and the FSIS line appears under the result.

Oven to air fryer temperature chart for a 400 °F air fryer

Oven recipe	Chicken, turkey, steaks, chops, roasts, ham	Other foods, such as ground meat, fish and vegetables
300 °F	325 °F (roast floor)	275 °F
325 °F	325 °F (roast floor)	300 °F
350 °F	325 °F	325 °F
375 °F	350 °F	350 °F
400 °F	375 °F	375 °F
425 °F	400 °F	400 °F
450 °F	400 °F (your max; converts to 425 °F)	400 °F (your max; converts to 425 °F)

The conversion formula, and the time windows it produces

\begin{aligned} T_{\text{air}} &= \min\!\Big(\max\big(\operatorname{round}_5(T_{\text{oven}} - 25),\ F\big),\ M\Big) \\[6pt] t_{\text{low}} &= \lfloor 0.75\, t_{\text{oven}} \rfloor \qquad t_{\text{high}} = \lceil 0.80\, t_{\text{oven}} \rceil \end{aligned}

$T_{\text{oven}}$ = the oven temperature printed in the recipe, in °F
$T_{\text{air}}$ = the air fryer setting the calculator shows
$F$ = the roasting floor, 325 °F for chicken or turkey, steaks, chops and roasts, and ham; other foods skip this step
$M$ = your air fryer's top setting: 390, 400 or 450 °F
$t_{\text{oven}}$ = the oven time in minutes
$t_{\text{low}},\ t_{\text{high}}$ = the short and long ends of the air fryer time window, in whole minutes

The air fryer setting is the oven temperature minus 25 °F, rounded to the nearest 5 degrees, raised to 325 °F if the food has a roasting floor and lowered to your air fryer's top setting if it lands above it. The time window runs from 75 percent of the oven time, rounded down to a whole minute, to 80 percent, rounded up. For chicken at 400 °F for 25 minutes that gives 375 °F and 18–20 minutes, since 25 × 0.75 = 18.75 and 25 × 0.80 = 20.

In °C the rounding happens on the Celsius figure. The 25 °F difference is the 14 °C that LG quotes, and after rounding to the nearest 5 °C a recipe temperature ending in 0 or 5 comes out 15 °C lower unless the floor or the cap applies: 200 °C gives 185 °C and 180 °C gives 165 °C. On the Celsius side the floor shows as 165 °C and the three top settings as 200, 205 and 230 °C.

The time rule changes in three cases. A convection recipe keeps its temperature, still rounded, floored and capped, and gets 80 to 100 percent of the time. Frozen packaged food opens its window at 50 percent. In the air fryer to oven direction the temperature goes up 25 °F and the time is divided instead, from the air fryer time ÷ 0.80, rounded down, to ÷ 0.75, rounded up, so 20 air fryer minutes become 25–27 in the oven and 25 become 31–34.

Oven time	Regular recipe	Convection recipe	Frozen packaged food
10 min	7–8 min	8–10 min	5–8 min
15 min	11–12 min	12–15 min	7–12 min
20 min	15–16 min	16–20 min	10–16 min
25 min	18–20 min	20–25 min	12–20 min
30 min	22–24 min	24–30 min	15–24 min
45 min	33–36 min	36–45 min	22–36 min
60 min	45–48 min	48–60 min	30–48 min

The shake-or-flip time is half the long end of the window, rounded to a whole minute, so an 18–20 minute window gets its flip at 10. Egg dishes, casseroles, baked goods and stuffed chicken get no shake prompt, only a time to start checking; so do windows whose long end is under 6 minutes, and every result in the air fryer to oven direction.

Oven to air fryer mistakes that leave the center undercooked

Taking 25 °F off a convection recipe. LG's convection modes set the oven 25 °F (14 °C) below a regular bake, so a convection recipe has already had its cut. A second 25 °F puts the air fryer 50 °F under the regular-oven version. Switch on "Recipe is for a convection (fan) oven" and only the time comes down.
Treating the converted time as the finish line. The time card gives a window and a first check, and the line under the cards calls the result "A starting point, not a doneness guarantee". FSIS asks for each food's minimum internal temperature, measured with a food thermometer, and Nebraska Extension calls the thermometer the only way to be sure meat, poultry and egg products are safe when air frying.
Pulling chicken a few degrees short and counting on carryover. Taking chicken out at 160 °F and letting the rest carry it to 165 °F skips the check FSIS asks for: its chart wants the minimum reached, measured with a thermometer, before the food comes off the heat. The 3-minute rest on that chart belongs to steaks, chops, roasts and raw ham, after they reach 145 °F.
Judging doneness by color. FSIS says ground beef may turn brown before it is safe, and that lasagna or egg casseroles may brown on top before they heat through. Push the thermometer into the center, at the spot the card names.
Roasting chicken or a pork loin below 325 °F. FoodSafety.gov's roasting charts start at an oven setting of 325 °F (163 °C), and a 325 °F recipe converts to 300 °F, under that line. The calculator raises chicken, turkey, whole cuts and ham back to 325 °F and says so under the cards. Ground meat and sausage fall outside FoodSafety.gov's roasting page and keep the converted setting.
Expecting the air fryer to reach the converted setting. The Ninja AF100 and AF140 and the Cosori Lite top out at 400 °F and the Philips Viva HD9220 at 390 °F, so the 425 °F a 450 °F recipe converts to is out of reach on all four. Set your model's top in "Air fryer’s top setting", and when the cap applies, plan on the long end of the window or more.
Filling the basket to the brim. FSIS warns that overcrowding can block the air circulation food needs to cook, and that an overfilled basket cooks unevenly and can leave food undercooked; it suggests cooking a large amount in batches. The calculator's window has no setting for a crowded basket.
Converting a box that already prints air fryer directions. FSIS says to follow the manufacturer's instructions on the package when they are available. Convert only when the box gives oven directions alone.
Reading a steak doneness chart as the safety target. Rare and medium-rare on a doneness chart are taste preferences. USDA's minimum for beef, pork, veal and lamb steaks, chops and roasts is 145 °F with a 3-minute rest, the figure the calculator's card shows.

What the conversion can't account for

The calculator has no input for wattage, basket size, how full the basket is or how thick the food is, and each of those moves the time. Use the window to plan the first check and the thermometer to decide when to stop.

When the top setting caps the temperature, the time is left as the rule gives it. The capped line tells you to expect the long end of the window or more, because the food is cooking cooler than the recipe intended. When the roasting floor raises the setting, the window also stays as the rule gives it.

The window counts from the moment the food goes in. Ninja recommends a 3-minute preheat for its AF100 and AF140, done before the food is added. Timers differ as well: the Philips Viva HD9220's stops at 30 minutes, and the Ninja AF100 and AF140 and the Cosori Lite stop the Air Fry timer at 60, which the calculator flags when the window runs past an hour.

There is no setting for basket versus oven-style air fryers beyond the top temperature, because Ninja's basket models and Cosori's air fryer oven publish the same 25 °F drop. Baked goods and vegetables have no USDA minimum, so they get the same rule and a card that says to cook to the recipe's own cue. In the air fryer to oven direction there is no oven cap, and an air fryer setting typed above 450 °F gets a line asking you to check it.

On the safe-temperature card and in the USDA table, the °C values are FoodSafety.gov's whole numbers: 74, 71, 63 and 60 °C. The FSIS chart prints the same limits to one decimal, as 73.9, 71.1 and 62.8 °C.

Oven to air fryer conversion questions

How do I convert oven temperature and time to an air fryer?

Take 25 °F off the oven setting and cook for 75 to 80 percent of the oven time, then check the food with a thermometer from the short end of that window. Type the recipe's temperature and minutes into the calculator and pick the food: a 400 °F, 25-minute chicken recipe gives 375 °F, 18–20 minutes and a 165 °F target in the thickest part.

What is 400 °F in an oven in an air fryer?

375 °F (190 °C). For a 30-minute oven time, plan on 22–24 minutes and check at 22. The other common settings follow the same 25 °F step: 350 °F becomes 325 °F, 375 °F becomes 350 °F and 425 °F becomes 400 °F.

How long do I air fry something that bakes for 30 minutes in the oven?

22 to 24 minutes, at 25 °F below the oven setting, with the first check at 22. A convection-oven recipe gets 24–30 minutes instead, and frozen packaged food with only oven directions gets 15–24, because its window opens at half the oven time.

Do I lower the temperature for a convection oven recipe in the air fryer?

No. LG's convection modes run 25 °F (14 °C) below a regular bake, and Whirlpool says air fryers and convection ovens may use similar temperatures, so the recipe's temperature carries over, still capped at your air fryer's top setting. Only the time changes, to 80 to 100 percent of the oven time. Switch on "Recipe is for a convection (fan) oven" in the calculator's folded settings.

My recipe says 450 °F but my air fryer only goes to 400 °F. What do I set?

Set 400 °F, the top. The rule gives 425 °F, more than a 400 °F model such as the Ninja AF100 or AF140 or the Cosori Lite can reach, so the calculator caps the result and says to expect the long end of the time or more; for a 20-minute recipe the window is 15–16 minutes. If your air fryer reaches 450 °F, pick that top setting and the result is 425 °F.

Can you cook frozen stuffed chicken breast, like chicken Kiev or cordon bleu, in an air fryer?

Not when the product is raw. USDA FSIS says not to cook raw, stuffed, breaded chicken breast products in an air fryer and to always follow the manufacturer's cooking instructions. In the calculator, "Stuffed breaded chicken" shows no air fryer setting at all, only the 165 °F (74 °C) the center of the filling has to reach. Check the label for the word raw, and follow the package.

What if a frozen food box only has oven directions?

Choose "Frozen packaged food" and convert the oven directions: the setting drops 25 °F and the window opens at half the oven time, after Instant's advice to cut frozen food's time by around 50 percent. A 20-minute box time gives a 10–16 minute window, first check at 10. When the box prints air fryer directions, use those, as FSIS advises.

What internal temperature should chicken reach in an air fryer?

165 °F (74 °C), measured with a food thermometer in the innermost part of the thigh and wing and the thickest part of the breast, before the chicken comes out. FSIS points out that air fryer cooking times vary with the appliance while the safe internal temperature stays the same.

How do I convert an air fryer recipe to the oven?

Add 25 °F and divide the time by 0.80 for the short end and 0.75 for the long end. Choose "Air fryer to oven", and a 400 °F, 25-minute air fryer recipe becomes 425 °F (220 °C) for 31–34 minutes, with "Start checking at 31 min". The top-setting choice disappears in this direction, and an air fryer temperature typed above 450 °F gets a line asking you to check it.

What is 200 °C or 180 °C in an air fryer?

185 °C for 200 °C, and 165 °C for 180 °C. The 25 °F drop is about 14 °C, LG's figure, and rounding to the nearest 5 °C makes it 15 °C lower for recipe temperatures ending in 0 or 5. Instant's UK chart takes 20 °C off, so its settings run 5 °C below the calculator's, while its times match on all six rows. The °F and °C fields keep separate values, so type the number your recipe prints.

Do I need to preheat the air fryer?

Follow your model's manual. Ninja recommends a 3-minute preheat for its AF100 and AF140 before the food goes in. The calculator's window starts when the food goes into the basket, so start counting then.

Can I bake cakes, muffins or cookies in an air fryer with this conversion?

Yes, as a starting point. With "Baked goods" chosen, a 350 °F, 30-minute recipe becomes 325 °F (165 °C) for 22–24 minutes, with "Start checking at 22 min" and no shake prompt. Whirlpool's advice for baking in an air fryer is the same 25 °F and 20 percent. Baked goods have no USDA minimum, so finish with the recipe's own test, such as a toothpick from the center.

Is an air fryer the same as a convection oven?

They cook the same way at different sizes: FSIS describes air fryers as essentially countertop convection ovens. Whirlpool puts both about 20 to 25 degrees below a conventional oven and says convection ovens may take slightly longer, which is why the calculator gives a recipe written for convection 80 to 100 percent of its time.

Why does the calculator give a time range instead of one number?

The makers' rules differ by a few minutes. Cosori and Whirlpool cut the oven time by 20 percent and Instant by 20 to 25 percent, so the window runs from 75 to 80 percent of the oven time. Instant's own UK chart prints windows too, and the calculator's times match all six of its rows: 20 oven minutes become 15–16, and 30 become 22–24. Check at the short end.

Is the oven to air fryer calculator free, and how close is its answer?

It is free to use. The temperature applies the 25 °F drop the makers publish, rounded to the nearest 5 degrees and kept within your air fryer's top setting, and the time window comes from their published percentages. Your model, the size of the load and the thickness of the food still move the real time, so use the window to time the first check and the third card's temperature to decide when the food is done.

What should I do if the food hasn't reached its temperature when the window ends?

Keep cooking and measure again a few minutes later, in the spot the card names. The window marks when to start checking. A thick cut, a full basket or a capped setting can run past its long end, and for chicken the target stays 165 °F however long that takes.

Does an air fryer cook faster than an oven?

For the same food, yes: the makers' rules take 20 to 25 percent off the oven time at 25 °F less heat. FSIS says foods generally need 5 to 25 minutes in an air fryer at 350 to 400 °F.
