Step 1 — eDPI is just DPI multiplied by your in-game sensitivity.

\text{eDPI} = \text{DPI} \times \text{sens} = 800 \times 2 = 1600

Step 2 — Each game has a yaw constant (degrees per mouse count). cm/360 is how many centimetres of mouse travel rotate your character a full 360°.

\text{cm/360} = \dfrac{360}{\text{yaw} \times \text{DPI} \times \text{sens}} \times 2.54 = \dfrac{360}{0.022 \times 800 \times 2} \times 2.54 = 25.9773\,\text{cm}

Step 3 — Convert centimetres to inches by dividing by 2.54.

\text{in/360} = \dfrac{\text{cm/360}}{2.54} = \dfrac{25.9773}{2.54} = 10.2273\,\text{in}

eDPI calculator. Effective DPI, cm/360 and inches/360 for any FPS.

An eDPI calculator multiplies your mouse DPI by your in-game sensitivity to give a single number that compares cleanly against any other player's setup. It also computes cm/360 and inches/360, the physical mouse distance for a full in-game turn, which is the only sensitivity metric that transfers between different FPS titles.

What is eDPI in FPS games?

eDPI (effective dots per inch) is your mouse DPI multiplied by your in-game sensitivity. It collapses two settings that affect aim speed into a single number, so two players running 800 DPI at 0.5 sens have the exact same eDPI (400) and the exact same on-screen cursor speed within that game as a player at 1600 DPI / 0.25 sens.
eDPI was popularised by competitive Counter-Strike and Valorant communities as a shorthand for comparing pro settings. It works perfectly inside one game, but it does not translate between titles. CS2 and Valorant use very different yaw constants (0.022 vs 0.07), so the same eDPI of 400 produces a 25.98 cm/360 turn in CS2 and only 8.16 cm/360 in Valorant — a totally different feel.
For cross-game comparison the community has converged on cm/360 (and its imperial equivalent inches/360): the physical distance your mouse must travel for the camera to complete a full 360-degree turn. Match cm/360 between two FPS games and your muscle memory transfers directly. Pros publish both numbers — eDPI for in-game peers, cm/360 for everyone else.
This calculator returns all three values at once for 14 FPS titles plus a custom-yaw mode. Pick a Source game and a Target game side by side and the calculator shows the target's equivalent in-game sensitivity at a glance — no dropdown-flipping or copy-pasting between sessions. When source and target match, it behaves like a standard single-game eDPI tool; when their yaw constants are identical (e.g. CS:GO and CS2, both 0.022), a banner confirms the sens transfers 1:1 and no conversion is needed. It uses the yaw constants verified against recharge.com's 2024–2025 published table, mouse-sensitivity.com's per-game converter pages, and rawaccel.co's sensitivity-converter constants — including the Rainbow Six Siege correction (0.00573, not Ubisoft's MouseSensitivityMultiplierUnit 0.00223) and the PUBG correction (0.002222, not 0.005556) that smaller community converters frequently get wrong.

How to calculate your eDPI and cm/360

There are two layers to the calculation. eDPI is a one-line multiplication; cm/360 needs your game's yaw constant. The calculator above does both automatically, but here is the manual version so you understand the result.
1. Find your mouse DPI in your mouse software (Logitech G Hub, Razer Synapse, SteelSeries GG, Windows Settings → Mouse). Most pro players sit between 400 and 1600 DPI; 800 has been the modal value for years.
2. Find your in-game sensitivity in the game's settings menu. In CS2 look under Settings → Mouse → Mouse Sensitivity; in Valorant under Settings → General → Sensitivity: Aim. Use the raw slider value, not Windows pointer speed.
3. Multiply the two numbers. eDPI = DPI × sensitivity. Example: 800 DPI at 0.4 Valorant sensitivity = 320 eDPI.
4. To get cm/360, divide 360 by (yaw × DPI × sensitivity), then multiply by 2.54. Example for the same Valorant setup: 360 / (0.07 × 800 × 0.4) × 2.54 = 40.82 cm. That is the physical distance your mouse hand needs to travel for a full in-game turn.
5. To get inches/360, divide cm/360 by 2.54. The Valorant example becomes 16.07 in/360.
In the calculator you only enter DPI and sensitivity and pick the game from the dropdown — the yaw constant is filled in automatically. For unsupported titles, switch the dropdown to "Other / Custom yaw" and paste the yaw value from your game's docs (or from the recharge.com 2024–2025 table).

  • DPIDPI = Mouse hardware DPI (e.g. 400, 800, 1600)
  • senssens = In-game sensitivity slider value
  • yawyaw = Game-specific yaw constant in degrees per mouse count (CS2 0.022, Valorant 0.07, Apex 0.022, OW2 0.0066, Warzone 0.0066, Fortnite 0.005555, R6 Siege 0.00573, PUBG 0.002222)
  • 2.542.54 = NIST-defined exact inch-to-centimetre conversion
eDPI is the simple one. Multiply DPI by sensitivity and you have a single number that compares cleanly with any other player's setup in the same game.
cm/360 is the cross-game metric and is where the yaw constant matters. yaw is the number of degrees your in-game camera turns per mouse count, baked into the game engine. Source-engine games (CS2, CSGO, Apex, TF2, Day of Defeat: Source, Quake Champions, Deadlock) all share yaw 0.022. Riot built Valorant on a custom Unreal stack with yaw 0.07. Call of Duty (Modern Warfare / Warzone) and Overwatch 2 both use 0.0066. Fortnite uses 0.005555 with a percent-style sensitivity slider. Rainbow Six Siege uses 0.00573 — 0.00223 is its MouseSensitivityMultiplierUnit, which is a different constant; converters that confuse the two are wrong.
The inches/360 value is purely cm/360 divided by 2.54. Players in the US, UK, and Australia tend to talk in inches/360; everywhere else cm/360 is the lingua franca.
The "sensitivity band" output (low / medium / high) classifies your cm/360 against per-game thresholds derived from observed pro distributions on prosettings.net, rather than a flat 20–80 cm scale. CS2's medium band is roughly 25–50 cm/360; Valorant 22–45; PUBG 12–30 (PUBG pros run famously high sens). The band is a sanity check, not a prescription.

eDPI calculator examples

Valorant — 800 DPI at 0.4 sensitivity (the modal Valorant setup)

An 800 DPI mouse at 0.4 in-game Valorant sens gives an eDPI of 320, a cm/360 of 40.82, and an inches/360 of 16.07. That sits in Valorant's medium band and matches the published settings of several Tier 1 pros from the 2023–2024 era. The calculator's "Closest pro" panel will surface a roster member within a few eDPI of this value.

CS2 vs Valorant — same eDPI, completely different feel

Set the calculator to CS2, enter 800 DPI / 0.4 sens. eDPI is still 320, but cm/360 jumps to 130.21 — wildly slow for CS2. That illustrates the core problem with copying eDPI between games: Valorant's yaw is 3.18× higher than CS2's, so the same eDPI is a totally different physical setup. To match a 40.82 cm/360 feel in CS2 you need eDPI ~ 1020 (e.g. 800 × 1.275). The calculator handles this comparison directly: change the game dropdown and watch eDPI stay constant while cm/360 swings.

Apex Legends — ImperialHal's settings

ImperialHal plays at 800 DPI and 1.1 sens (verified against prosettings.net 2026-05). Plug those in with Apex selected: eDPI 880, cm/360 47.23, inches/360 18.59. That's medium-band for Apex (Apex pros cluster a bit slower than CS2 pros because of the wide-angle FOV). If you currently aim at a 47 cm/360 in CS2 (eDPI ~ 360), copying ImperialHal will feel native day one.

Cross-game cm/360 reference table

Same physical 30 cm/360 turn translated across games (yaw values 2026-05-05): CS2 needs eDPI 1391 (e.g. 800 × 1.74); Valorant needs eDPI 437 (e.g. 800 × 0.546); Apex needs eDPI 1391 (Source-engine, identical to CS2); OW2 needs eDPI 4639 (yaw 0.0066, hence the famously high-eDPI Overwatch numbers); Fortnite needs eDPI 5513 (X-axis percent slider); R6 Siege needs eDPI 5346; PUBG needs eDPI 13783 (which is why PUBG pros publish 800/35-style configs).

Tips for using your eDPI and cm/360

  • Lock your DPI at 800 and tune the in-game sens. 800 is the modal pro DPI across CS2, Valorant, and Apex because it sits comfortably above sensor-skip thresholds while staying low enough that 1:1 in-game movement feels precise. Most modern sensors (PMW3360, HERO, Focus Pro 30K) are pixel-perfect from 100 DPI to 26,000 DPI, so 800 is not a hardware limit — it's a community convention that makes pro settings comparable.
  • Use cm/360, not eDPI, when switching games. eDPI 320 in Valorant feels nothing like eDPI 320 in CS2. Pick a cm/360 you already aim well at (most likely between 25 and 45) and convert in both directions. The calculator shows two game selectors side by side: pick your Source game (where your sens lives today), pick your Target game, and the equivalent in-game sensitivity for the target appears instantly next to the eDPI/cm360/in360 outputs.
  • Treat the sensitivity band as a sanity check, not a prescription. "High sens" in Valorant (cm/360 below 22) is faster than most ranked players and tougher to control under pressure. "Low sens" (above 45) sacrifices flick speed for precision. Most pros sit in medium for a reason — extremes punish you in either direction.
  • Match the closest pro only as a starting point. The pro roster shown in the calculator is verified against prosettings.net 2026-05-05, but a pro's setup is built on thousands of hours of muscle memory at that exact value. Use it to find a credible target, then run aim trainer drills (Aim Lab, Kovaak's, the in-game range) for at least two weeks before changing again. Constant tweaking is the single most common reason aim plateaus.
  • Disable Windows Enhance Pointer Precision and any in-game mouse acceleration. eDPI assumes a linear cursor response. Acceleration breaks that assumption and makes your effective sens drift with hand speed, which is a one-way ticket to inconsistent flicks. Check Settings → Bluetooth & Devices → Mouse → Additional mouse settings → Pointer Options.
  • If your game is not in the dropdown, use the "Other / Custom yaw" mode and paste the yaw constant from a published source. recharge.com publishes a 2024–2025 yaw table covering 23 FPS games; rawaccel.co publishes constants for less-common engines. Avoid using a yaw value scraped from a random forum post unless you can verify it against a second source.

Frequently asked questions about eDPI and cm/360

What is eDPI?

eDPI (effective dots per inch) is your mouse DPI multiplied by your in-game sensitivity. The formula is eDPI = DPI × sensitivity. It is a single number that lets you compare aim speed against any other player in the same game, regardless of what hardware DPI they use.

What is cm/360 and why does it matter more than eDPI?

cm/360 is the physical distance your mouse must travel for the camera to complete one full 360-degree turn in-game. It is calculated as 360 / (yaw × DPI × sens) × 2.54. cm/360 matters more than eDPI when you switch between FPS games, because each game uses a different yaw constant — so the same eDPI feels totally different in CS2 vs Valorant vs Overwatch.

What is a good eDPI for FPS games?

A good eDPI depends entirely on the game. Valorant pros cluster at 200–400 eDPI; CS2 pros at 400–1200; Apex pros at 800–1600; Fortnite pros at 1200–6400 (X-axis percent); Overwatch 2 pros at 4000–7200. Compare against the per-game ranges shown by this calculator's sensitivity band rather than a single universal target.

How do I convert sensitivity between games?

Match cm/360, not eDPI. Set the Source game to your starting title and enter your current DPI and sens, then set the Target game to your destination title — the equivalent in-game sensitivity for the target appears immediately alongside the eDPI, cm/360 and inches/360 outputs. Example: CS2 at 800 DPI / 1.0 sens → set target to Valorant and you'll see 0.314 sens instantly (same 51.95 cm/360). The yaw constants embedded in this calculator (verified May 2026) handle the math automatically.

Is this eDPI calculator free?

Yes. The calculator runs entirely in your browser, requires no signup, and stores no personal data. Your DPI, sensitivity, and game selection persist locally so the page reloads with your last setup, but nothing is sent to a server.

How accurate are the cm/360 values?

They are accurate to 0.01 cm against the canonical formula. The yaw constants for all 14 supported games were re-verified on 2026-05-05 against recharge.com's 2024–2025 yaw table, mouse-sensitivity.com per-game converter pages, and rawaccel.co. Two values that other converters frequently get wrong (Rainbow Six Siege 0.00573 and PUBG 0.002222) are correct here.

Does eDPI translate between Valorant and CS2?

No. Valorant's yaw (0.07) is 3.18× higher than CS2's (0.022), so the same eDPI value produces a turn that is 3.18× faster in Valorant. Copy your CS2 cm/360 instead — at 800 DPI and 1.0 CS2 sens (cm/360 ≈ 52), the matching Valorant setup is roughly 800 DPI and 0.314 sens (eDPI 251).

Should I copy a pro player's eDPI?

As a starting point only. A pro's cm/360 is a credible target — most pros sit in their game's medium band for a reason — but their exact value is built on thousands of hours of muscle memory. Use the closest-pro match in this calculator to land in the right neighbourhood, then commit for at least two weeks before adjusting. Constant tweaking is the most common cause of stagnant aim.

Why is my Valorant eDPI so different from my CS2 eDPI?

Because Valorant's yaw constant is 3.18× higher than CS2's, the same physical cm/360 turn requires a much lower in-game sensitivity in Valorant. Pros who switched from CS:GO/CS2 to Valorant (TenZ, ScreaM) typically run Valorant eDPI 250–350 vs CS:GO eDPI 800–1100 — same cm/360, very different eDPI.

What if my game is not in the dropdown?

Switch the game dropdown to "Other / Custom yaw" and paste the yaw value from your game's documentation or a verified published source like recharge.com's 2024–2025 yaw table. The calculator will then compute eDPI, cm/360 and inches/360 with that custom yaw.

Is higher eDPI better for FPS aim?

No. Higher eDPI gives faster turns and quicker target acquisition but punishes precision. Lower eDPI rewards precise headshot aim but requires more arm space. Most pros across CS2, Valorant, and Apex sit in their game's medium band; the optimum is whichever cm/360 you can hold steady when shooting under pressure, not the highest or lowest you can tolerate.

Mouse sensitivity glossary

eDPI

Effective dots per inch. eDPI = DPI × in-game sensitivity. A single number that compares aim speed against other players in the same game.

DPI

Dots per inch — a hardware setting on the mouse itself that defines how many sensor counts are reported per inch of physical movement. Most pros use 400, 800, or 1600.

In-game sensitivity

The sensitivity slider value inside the game's settings menu (e.g. CS2 "Mouse Sensitivity", Valorant "Sensitivity: Aim"). Multiplied by DPI and the game's yaw constant to determine on-screen turn speed.

cm/360

Centimetres of physical mouse travel needed to complete one full 360-degree turn in-game. The metric pros publish for cross-game comparison because it is independent of yaw.

inches/360

The imperial equivalent of cm/360. inches/360 = cm/360 ÷ 2.54. Common in US, UK and Australian community discussion.

Yaw constant

The number of degrees the camera turns per mouse count, baked into each game engine. CS2 0.022, Valorant 0.07, Apex 0.022, OW2 0.0066, Warzone 0.0066, Fortnite 0.005555, R6 Siege 0.00573, PUBG 0.002222.

Sensitivity band

A low / medium / high classification of your cm/360 relative to that game's typical pro distribution. CS2 medium ≈ 25–50 cm/360; Valorant medium ≈ 22–45; PUBG medium ≈ 12–30.

Closest pro match

The pro player from a curated, prosettings.net-verified roster whose published DPI × sensitivity is mathematically nearest to the user's eDPI for the selected game.

Polling rate

How many times per second the mouse reports its position to the PC, measured in Hz. Standard values are 125, 500, 1000, 2000, 4000, and 8000 Hz. Polling rate does not affect eDPI or cm/360, only motion smoothness.

Raw input

A toggle in many FPS games that bypasses Windows Enhance Pointer Precision and other OS-level mouse processing. Always enable it; it is what makes eDPI a stable metric in the first place.
