Results

Effective DPI (eDPI)

1600

An eDPI of 1600 in CS:GO means a full 360° turn takes 26.0 cm (10.2 in) of mouse movement. eDPI only compares settings inside one game, because every game turns a different number of degrees per mouse count; use cm/360 when you move between games. There is no single correct value: pick a turn distance that fits your desk and arm, then give it a week before changing it.

How eDPI Calculator Works

eDPI = DPI × Sensitivity | cm/360 = 360 × 2.54 ÷ (DPI × Sensitivity × yaw)

Effective DPI (eDPI) is your mouse DPI multiplied by your in-game sensitivity. It tells you how fast the cursor turns inside one game. To compare games, use the distance your mouse travels for a full turn (cm/360), which depends on each game's yaw: the degrees it turns per mouse count at sensitivity 1.

DPI, Sens
DPI & In-Game Sensitivity — Mouse DPI is hardware sensitivity. In-game sensitivity is the software multiplier. Together they determine cursor speed.
eDPI
Effective DPI — The product of DPI and sensitivity, providing a standardized measure of cursor speed inside one game.
yaw
Game yaw — Degrees the game turns per mouse count at sensitivity 1 (CS 0.022, Valorant 0.07, Overwatch 0.0066). It is what makes the same sensitivity number feel different in each game.
cm/360
Distance per full turn — How far the mouse travels for a 360 degree turn. Divide by 2.54 for inches per 360.

Source: The cm/360 formula uses each game's yaw constant, the degrees turned per mouse count at sensitivity 1: 0.022 for CS, Apex and Quake Champions, 0.07 for Valorant, 0.0066 for Overwatch 2 and Call of Duty, 0.00573 for Rainbow Six Siege and 0.002222 for PUBG. Game multipliers are the ratios of those constants to CS's 0.022 (Valorant 0.3143, Overwatch 3.333, Rainbow Six Siege 3.840). These are community-published constants, listed identically by csdb.gg and by a Portuguese-language tabnews.com.br article; they were not measured in game for this page.

eDPI = DPI × Sensitivity standardizes cursor speed inside one game. Different DPI/sensitivity combinations can produce the same eDPI.

Worked Examples

A CS2 player at 800 DPI, 1.1 sensitivity switches to Valorant

mouseDpi = 800 · sensitivity = 1.1 · currentGame = CS:GO · targetGame = Valorant

eDPI 880 → Valorant sensitivity 0.3457

Multiplying CS sensitivity by 0.3143 preserves your exact cm/360 (≈47 cm), so years of muscle memory transfer instantly instead of rebuilding from scratch.

Two friends argue whose sensitivity is "faster": 400 DPI × 3.0 vs 1600 DPI × 0.75

mouseDpi = 400 · sensitivity = 3.0 · currentGame = CS:GO

Both are 1200 eDPI — identical speed

DPI and in-game sensitivity are interchangeable multipliers. The only real difference: higher DPI with lower sens gives smoother low-speed tracking on most sensors.

An Overwatch player at 800 DPI, 6.0 sensitivity wants the distance for a full turn

mouseDpi = 800 · sensitivity = 6.0 · currentGame = Overwatch

eDPI 4800 → 28.9 cm per 360°

Overwatch sensitivity numbers run about 3.3× larger than CS for the same physical speed (its yaw is 0.0066 against 0.022 for CS), so comparing raw eDPI across games is meaningless without the game multiplier.

A Valorant player at 800 DPI, 0.4 sensitivity wants the CS2 equivalent

mouseDpi = 800 · sensitivity = 0.4 · currentGame = Valorant · targetGame = CS:GO

eDPI 320 → 40.8 cm per 360° → CS2 sensitivity 1.2727

The eDPI jumps from 320 to 1018 (800 × 1.2727) but the turn distance stays 40.8 cm, which is the whole point of converting by yaw.

A player at 400 DPI wants a 25 cm/360 in CS2

mouseDpi = 400 · currentGame = CS:GO · targetCm360 = 25

Sensitivity 4.1564 (eDPI 1663)

360 × 2.54 ÷ (400 × 25 × 0.022) = 4.1564. Enter a target cm/360 whenever you want a specific turn distance instead of copying a number.

Understanding the Result

eDPI (Effective Dots Per Inch) is your mouse DPI multiplied by your in-game sensitivity. Two players with the same eDPI in the same game turn the same amount for the same hand movement, even if one uses 400 DPI at 4 sensitivity and the other 800 DPI at 2 sensitivity (both 1600 eDPI). eDPI on its own does not carry across games, because each game turns a different number of degrees per mouse count (its yaw).

To compare games, use cm/360, the distance your mouse travels for a full turn: cm/360 = 360 × 2.54 ÷ (DPI × sensitivity × yaw). At 800 DPI and 2.0 sensitivity in CS2 that is 360 × 2.54 ÷ (800 × 2.0 × 0.022) = 26.0 cm, or 10.2 inches. To move a sensitivity to another game while keeping cm/360, multiply by the ratio of the two yaw values. CS2 to Valorant is 0.022 ÷ 0.07 = 0.3143, so a CS2 sensitivity of 2.5 becomes 2.5 × 0.3143 = 0.786 in Valorant at the same DPI.

Going the other way, multiply a Valorant sensitivity by 3.1818. You can also work backwards: the sensitivity for a target cm/360 is 360 × 2.54 ÷ (DPI × cm/360 × yaw). This calculator assumes raw input with no mouse acceleration. If Windows pointer speed is not at the default 6/11, or "Enhance pointer precision" is on, the real sensitivity drifts away from the maths. Games with a separate scoped (ADS) sensitivity need that value matched on its own.

How to Use

  1. Enter your mouse DPI (usually found in your mouse software or settings). CPI is the same number.
  2. Enter your in-game sensitivity from your current game.
  3. Select which game you are currently playing.
  4. Read your eDPI, cm/360 and inches/360. The reference tables show the same turn distance in every supported game.
  5. Optionally pick a target game to convert your sensitivity, or enter a target cm/360 to get the sensitivity that produces it.

Frequently Asked Questions

What is eDPI?
eDPI stands for effective DPI. It is your mouse DPI multiplied by your in-game sensitivity, for example 800 DPI × 0.4 = 320 eDPI. It lets you compare two setups that use different DPI, as long as both are in the same game.
How do I calculate eDPI?
Multiply the DPI of your mouse by the sensitivity in the game. 400 DPI × 3.0 = 1200 eDPI, and 1600 DPI × 0.75 = 1200 eDPI as well. Enter both numbers above and the calculator also gives your cm/360.
How do I convert eDPI to cm/360?
cm/360 = 360 × 2.54 ÷ (eDPI × yaw), where yaw is the game's degrees per mouse count (0.022 for CS2 and Apex, 0.07 for Valorant, 0.0066 for Overwatch 2). 1600 eDPI in CS2 is 360 × 2.54 ÷ (1600 × 0.022) = 26.0 cm. The same 1600 eDPI in Valorant would be only 8.2 cm, which is why eDPI cannot be compared between games. The table under the results lists eDPI against cm/360 for several games.
What is a good eDPI for Valorant?
There is no official good number. What matters is the turn distance it produces. For example 800 DPI × 0.4 is 320 eDPI, which is 40.8 cm per 360 in Valorant, while 320 eDPI in CS2 would be 129.9 cm. Pick a cm/360 that fits your mousepad and arm, test it for a week, and use the cm/360 shown here to compare with other players. Published pro settings change over time, so check a current database such as ProSettings.net rather than relying on a figure printed here.
How do I convert sensitivity from CS:GO or CS2 to Valorant?
Multiply your CS sensitivity by 0.3143 (0.022 ÷ 0.07) and keep the same DPI. Example: 1.1 in CS2 becomes 1.1 × 0.3143 = 0.3457 in Valorant, which gives the same distance per 360. To go from Valorant to CS2, multiply by 3.1818. Choose the games in the calculator above to do it for any pair.
What is cm/360 and inches/360?
cm/360 is the distance in centimetres your mouse must travel for the game to turn a full 360 degrees; inches/360 is the same distance in inches (divide cm by 2.54). It does not depend on the game once measured, so it is the number to match when you switch games.
Why does the same eDPI feel different in different games?
Each game converts a mouse count into a different angle (its yaw). 800 eDPI turns a full circle in about 52.0 cm in CS2, 16.3 cm in Valorant and 173.2 cm in Overwatch 2, so raw eDPI values from different games cannot be compared.
Why does eDPI matter for muscle memory?
Muscle memory in aim is built around the physical distance your hand moves to achieve a specific rotation in-game. eDPI (and cm/360) normalizes this so that regardless of DPI or sensitivity settings, the same hand movement produces the same in-game rotation.
How do I find my mouse DPI?
Check your mouse manufacturer's software (Logitech G Hub, Razer Synapse, SteelSeries GG, etc.). Most gaming mice have on-the-fly DPI adjustment buttons. You can also measure your DPI using online DPI analyzers.
Is CPI the same as DPI for mouse sensitivity?
Yes. CPI (counts per inch) is the technically accurate term for what mouse sensors actually measure, while DPI (dots per inch) is the marketing term manufacturers use for the same spec — they describe the identical value and can be entered interchangeably in this calculator. A mouse listed at "800 DPI" reports 800 counts per inch of physical movement. There is no conversion needed between them; if a product page or software shows CPI instead of DPI, use that same number directly as the Mouse DPI input above.
Why is Fortnite not in the list?
Fortnite uses a percentage slider, and the published conversion constants I found for it disagree with each other. Rather than show a number that may be wrong, it is left out. Measure your cm/360 in Fortnite directly, then enter it as the target cm/360 above to get the equivalent in the supported games.
How do I match my sensitivity between games that are not in this list?
Use the 360-degree turn method. Measure how many centimetres your mouse moves to perform a full 360-degree turn in your current game. In the new game, adjust the sensitivity until the same mouse movement produces exactly one full turn. Source engine games such as Counter-Strike, Team Fortress 2 and Left 4 Dead use the same scale, so the same number gives the same cm/360. Make sure Windows pointer speed is at the default 6/11 and "Enhance pointer precision" is off, and match scoped (ADS) sensitivity separately.

Pro Tips

  • →Set your mouse to a native DPI step (400/800/1600) — odd values like 1350 are interpolated on some sensors and add jitter.
  • →Disable "Enhance pointer precision" in Windows and keep pointer speed at 6/11, or your real sensitivity will drift from the math.
  • →When changing your cm/360, change it once and commit for at least a week — constant tweaking destroys the muscle memory you are trying to build.
  • →Match your ADS/scope multiplier separately when switching games; the hipfire conversion alone does not carry it over.
  • →Use cm/360 (shown in your results) as your portable number — it does not depend on the game once measured.

Limitations to Know

  • •Game multipliers assume default FOV and raw input; some games scale sensitivity with FOV, which changes the effective feel even at identical cm/360.
  • •cm/360 uses each game's published yaw constant (CS, Apex and Quake Champions 0.022, Valorant 0.07, Overwatch 2 and Call of Duty 0.0066, Rainbow Six Siege 0.00573, PUBG 0.002222); other games, including Fortnite, are not covered.
  • •Console and controller sensitivities use entirely different (aim-acceleration) systems and cannot be converted with eDPI.
  • •There is no "correct" eDPI or cm/360. The numbers here describe your setup, they do not rate it.
