This free eDPI calculator and sensitivity converter gives you three things at once: your eDPI, your cm/360° (how far you move the mouse for a full turn), and the equivalent sensitivity in every major FPS — so your aim feels identical when you switch games.
What is eDPI?
eDPI (effective DPI) is simply your mouse DPI × in-game sensitivity. It's the fairest way to compare sensitivity between players in the same game, because it combines both settings into one number. For example, 800 DPI at 1.0 sensitivity and 400 DPI at 2.0 sensitivity are both 800 eDPI — they aim the same. Most Valorant and CS2 pros sit somewhere around 200–400 and 700–1000 eDPI respectively.
What is cm/360 and why is it better across games?
eDPI only compares fairly within one game, because each game scales sensitivity differently. cm/360° — the physical distance you slide the mouse to spin a full 360° — is the truly game-agnostic measure. Keeping the same cm/360° when you switch titles preserves your muscle memory. This converter calculates it with cm/360 = 914.4 ÷ (yaw × sens × DPI), where yaw is each game's rotation constant.
How sensitivity conversion works
To match your turn across games, the converter uses target sens = source sens × (source yaw ÷ target yaw). CS2, CS:GO and Apex Legends all use the Source-engine yaw of 0.022, so they convert 1:1. Valorant runs about 3.18× slower on paper (CS2 ÷ 3.18 = Valorant), and Overwatch 2 and Warzone share a faster 0.0066 yaw (OW2 ÷ 3.33 = CS2).
Frequently asked questions
How do I calculate eDPI?
eDPI = mouse DPI × in-game sensitivity. For example, 800 DPI × 0.5 sensitivity = 400 eDPI. It's the standard way to compare sensitivity between players in the same game.
What is a good eDPI for Valorant or CS2?
Most Valorant pros land around 200–400 eDPI, and most CS2 pros around 700–1000 eDPI. Lower eDPI means slower, more precise aim; there's no single "correct" value — consistency matters more.
How do I convert my sensitivity from Valorant to CS2?
Multiply your Valorant sensitivity by 3.18 to get CS2 (and divide CS2 by 3.18 to go back). This keeps the same cm/360° so your aim carries over.
Do CS2 and Apex Legends use the same sensitivity?
Yes. Both use the Source-engine yaw of 0.022, so your CS2 sensitivity works 1:1 in Apex Legends with no conversion needed.
Is cm/360 better than eDPI?
For comparing across different games, yes — cm/360° reflects the real-world mouse distance for a full turn, while eDPI only compares fairly within the same game.
