Shoe Size Converter: EU to UK Cups to Grams Converter

Cooking Converter. Convert cups, tablespoons, grams, and more between any cooking units.

A cooking converter translates between 10 volume and weight units, including cups, tablespoons, mL, grams, and pounds. For volume-to-weight conversions it applies ingredient-specific densities, since one cup of flour weighs 125 g while one cup of honey weighs 340 g.

What Is a Cooking Measurement Converter?

A cooking measurement converter is a tool that translates between different units used in recipes, including cups, tablespoons, teaspoons, fluid ounces, milliliters, liters, grams, kilograms, ounces, and pounds. It handles conversions within the same measurement type (volume to volume, weight to weight) and across measurement types (volume to weight and back), which requires knowing the specific ingredient's density.

This converter solves a problem every home cook encounters: recipes come from all over the world and use different measurement systems. An American recipe uses cups and ounces, a European one uses grams and milliliters, and a British one might use imperial pints (which are different from US pints). Converting between these systems accurately means the difference between a recipe that works perfectly and one that fails.

Our universal cooking converter supports 10 units across both volume and weight. When you convert between volume and weight (for example, cups to grams), it prompts you to select the specific ingredient because each ingredient has a unique density. One cup of flour weighs 125 g, while one cup of honey weighs 340 g.

How to Convert Between Cooking Measurements

Converting between cooking measurements follows different rules depending on whether you are converting within the same measurement type or across types.

For volume-to-volume or weight-to-weight conversions (same type), use a fixed conversion factor:

1. Identify the source and target units (e.g., tablespoons to milliliters).

2. Look up the conversion factor (1 US tablespoon = 14.79 mL).

3. Multiply the source value by the factor.

For volume-to-weight or weight-to-volume conversions (crossing types), you need the ingredient's density:

1. Identify the source unit, target unit, and the specific ingredient.

2. Convert the source value to a base unit (mL for volume, grams for weight).

3. Apply the ingredient's density to cross between volume and weight.

4. Convert to the target unit.

For example, to convert 2 cups of all-purpose flour to grams: 2 cups x 236.59 mL/cup = 473.18 mL. Flour density = 0.529 g/mL. So 473.18 x 0.529 = 250.3 g (or simply 2 x 125 g/cup = 250 g).

Our converter handles all of this automatically. Just select your units, enter a value, and choose an ingredient if crossing between volume and weight.

Cooking Conversion Formulas

V_{target} = V_{source} \times \frac{F_{source}}{F_{target}}

$V_{target}$ = Value in the target unit
$V_{source}$ = Value in the source unit
$F_{source}$ = Conversion factor from the source unit to the base unit
$F_{target}$ = Conversion factor from the target unit to the base unit

For volume-to-volume conversions, the base unit is milliliters. Common factors:

- 1 teaspoon = 4.929 mL - 1 tablespoon = 14.787 mL - 1 fluid ounce = 29.574 mL - 1 cup = 236.588 mL - 1 liter = 1,000 mL

For weight-to-weight conversions, the base unit is grams:

- 1 ounce = 28.3495 g - 1 pound = 453.592 g - 1 kilogram = 1,000 g

When crossing between volume and weight, the density bridges the two:

W_g = V_{mL} \times \rho

Where the density (rho) is the ingredient's mass per unit volume in g/mL. For example, water has a density of approximately 1.0 g/mL, butter is about 0.959 g/mL, and all-purpose flour is about 0.529 g/mL.

Cooking Measurement Conversion Examples

Converting a European Cake Recipe to US Measurements

A French recipe calls for 250 g flour, 150 g sugar, 100 mL milk, and 75 g butter. Converting to US measurements:

- 250 g flour = 250 / 125 = 2 cups - 150 g sugar = 150 / 200 = 3/4 cup - 100 mL milk = 100 / 236.59 = 0.42 cups, or about 6.5 tablespoons - 75 g butter = 75 / 227 = 0.33 cups, or about 5.3 tablespoons

Note how some conversions produce clean cup fractions (2 cups, 3/4 cup) while others produce awkward numbers. This is why metric measurements are actually easier to scale.

Scaling a Recipe from 4 Servings to 10 Servings

A soup recipe for 4 servings uses 2 tablespoons of olive oil, 3 cups of broth, and 8 oz of chicken. You need to scale to 10 servings (multiply by 2.5):

- 2 tbsp x 2.5 = 5 tbsp olive oil = 5 x 14.79 = 73.9 mL (about 75 mL) - 3 cups x 2.5 = 7.5 cups broth = 7.5 x 236.59 = 1,774 mL (about 1.8 liters) - 8 oz x 2.5 = 20 oz chicken = 20 x 28.35 = 567 g

Converting to metric first makes the math cleaner, especially for large batches.

Converting Fluid Ounces to Cups for a Cocktail Recipe

A cocktail recipe calls for 3 fl oz of bourbon, 1 fl oz of sweet vermouth, and 0.5 fl oz of simple syrup. To convert to metric: 3 fl oz = 88.7 mL, 1 fl oz = 29.6 mL, 0.5 fl oz = 14.8 mL. Total = 133.1 mL, which is just over half a cup (118.3 mL). This type of conversion is handy when preparing large punch bowls where measuring in cups is faster than counting fluid ounces.

Tips for Using a Cooking Measurement Converter

Always identify whether you need a volume-to-volume, weight-to-weight, or volume-to-weight conversion before starting. Volume-to-volume and weight-to-weight conversions use a fixed factor and don't require knowing the ingredient. Volume-to-weight conversions require the ingredient's density.
When a recipe lists ingredients in both volume and weight (e.g., "1 cup / 125 g flour"), use whichever one your measuring tools support. If you have a scale, the gram value is more reliable.
Liquid ingredients like water, milk, and juice have densities close to 1 g/mL, so 100 mL of a liquid weighs approximately 100 g. This rule of thumb breaks down for thick liquids like honey (1.42 g/mL) or light liquids like oil (0.92 g/mL).
For baking, weight measurements (grams, ounces) are always more accurate than volume measurements (cups, tablespoons). Professional bakers worldwide prefer weight-based recipes because they eliminate variability from ingredient packing, humidity, and measuring technique.
When converting teaspoons to milliliters for spices and extracts, note that 1 US teaspoon = 4.93 mL and 1 metric teaspoon = 5 mL. The difference is small but matters for potent ingredients like baking soda or vanilla extract.
US fluid ounces and imperial (UK) fluid ounces are not the same. A US fluid ounce = 29.57 mL while a UK fluid ounce = 28.41 mL. A UK pint is 568 mL versus 473 mL for a US pint. Always check which system the recipe uses.

Frequently Asked Questions About Cooking Conversions

How many tablespoons are in a cup?

There are exactly 16 US tablespoons in 1 US cup. This means 1/4 cup = 4 tablespoons, 1/3 cup = 5.33 tablespoons, and 1/2 cup = 8 tablespoons. This is one of the most useful cooking equivalencies to memorize.

How many teaspoons are in a tablespoon?

In the US and metric systems, 1 tablespoon equals 3 teaspoons. In Australia, 1 tablespoon equals 4 teaspoons. This is a fundamental kitchen conversion: 1 US tablespoon = 3 tsp = 14.79 mL.

Why can't I simply convert cups to grams without selecting an ingredient?

Because cups measure volume and grams measure weight. The same volume of different ingredients weighs different amounts due to density differences. One cup of water weighs 237 g, one cup of flour weighs 125 g, and one cup of honey weighs 340 g. You must specify the ingredient so the converter can apply the correct density.

How many cups are in a liter?

One liter equals approximately 4.227 US cups (since 1 liter = 1,000 mL and 1 US cup = 236.59 mL). For a quick approximation, 1 liter is roughly 4 and 1/4 cups. If using metric cups (250 mL), one liter equals exactly 4 metric cups.

What is the difference between a dry ounce and a fluid ounce?

A dry ounce (oz) is a unit of weight equal to 28.35 g. A fluid ounce (fl oz) is a unit of volume equal to 29.57 mL. They measure different physical properties. One fluid ounce of water happens to weigh approximately 1.04 dry ounces, but for other substances the relationship is different. One fluid ounce of honey weighs about 1.5 dry ounces because honey is denser than water.

How do I convert a recipe from US measurements to metric?

Replace volume measurements with grams using ingredient-specific conversions: cups of flour become grams (1 cup = 125 g), cups of sugar become grams (1 cup = 200 g), and liquid cups become milliliters (1 cup = 237 mL). Replace ounces with grams (1 oz = 28.35 g) and Fahrenheit with Celsius ((F - 32) x 5/9). Our converter handles all of these translations automatically.

Are UK and US cups the same size?

No. The US cup is 236.59 mL while the now-obsolete UK imperial cup was 284.13 mL. However, modern UK recipes rarely use cups at all; they typically use grams and milliliters. If you encounter cups in a UK recipe, check whether the author specifies US cups (common in modern UK food blogs) or imperial cups (rare, mostly in vintage cookbooks).

How many mL are in a US cup?

One US cup equals 236.588 mL. For quick math, round to 237 mL. This is different from a metric cup (250 mL) and the imperial cup (284 mL). When using a graduated measuring cup marked in milliliters, measure to 237 mL to get exactly one US cup.

Volume Measurement

A measurement of the space an ingredient occupies, expressed in units like cups, tablespoons, teaspoons, fluid ounces, milliliters, and liters.

Weight Measurement

A measurement of how heavy an ingredient is, expressed in units like grams, kilograms, ounces, and pounds. Generally more precise than volume for dry ingredients.

Density

The ratio of an ingredient's mass to its volume (g/mL). Determines how much a given volume of an ingredient weighs. Essential for converting between cups and grams.

US Cup

A unit of volume equal to 236.588 mL or 8 US fluid ounces. The standard cup measurement in American recipes.

Metric Cup

A unit of volume equal to 250 mL, used in Australia, New Zealand, and Canada. Approximately 5.7% larger than the US cup.

Fluid Ounce

A unit of volume equal to 29.5735 mL (US) or 28.4131 mL (UK imperial). Not to be confused with the weight ounce.

Tare Function

A feature on digital kitchen scales that resets the display to zero after placing a container on it, so you can measure only the weight of the ingredient added.
