Sensitivity Converter
Convert your sensitivity between Overwatch, Valorant, CS2, Apex Legends, Fortnite, Marvel Rivals, and Call of Duty. Uses documented yaw values for accurate conversion. Pair pages with their own write-ups exist only for Overwatch, Valorant, CS2, and Apex — the yaw figures I could verify.
Converted Sensitivity
0.471
This tool converts sensitivity values using the monitor distance coefficient (yaw angle per mouse count). Each game has a different yaw value that determines how much you turn for each unit of mouse movement. The converter uses these documented values to maintain the same physical cm/360 distance across games.
Dedicated pair pages: Overwatch to Valorant sensitivity, Valorant to Overwatch sensitivity, Valorant to CS2 sensitivity, CS2 to Valorant sensitivity, CS2 to Overwatch sensitivity, Overwatch to CS2 sensitivity, Apex to CS2 sensitivity, CS2 to Apex sensitivity.
Read more about sensitivity in how to find your sensitivity and what mouse DPI means. Field of view is a different number: use the FOV converter.
cm/360 Calculator
Calculate your cm/360 (centimeters per 360-degree turn) from your DPI and in-game sensitivity. This physical measurement lets you compare settings across different games and setups.
Your cm/360
34.64 cm
Your cm/360 is how far you move your mouse to turn 360 degrees in-game. It's a physical measurement independent of any specific game. Most competitive FPS players use 20-40 cm/360, though preferences vary by role and game.
Learn more in best aim training.
eDPI Calculator
Calculate your effective DPI (eDPI) by multiplying your mouse DPI and in-game sensitivity. It is a quick way to compare sensitivities inside the same game.
Use the in-game value, decimals allowed (for example 0.33 in Valorant)
Your eDPI
400
Common eDPI ranges:
- • Low sens: 200-400 eDPI
- • Medium sens: 400-800 eDPI
- • High sens: 800+ eDPI
eDPI (effective DPI) is your mouse DPI multiplied by your in-game sensitivity. It's useful for quickly comparing settings with other players in games like Valorant and CS2 that use decimal sensitivity values. However, cm/360 is more universal since it works across all games.
See mouse DPI and mouse polling rate for related settings. Check the rate this browser can see with the polling-rate tester.

Common questions
Why are my converted sensitivities different from other calculators?
Calculators can use slightly different yaw values, especially for older games. This tool uses the current documented values, and differences under 1% are just rounding.
Should I use the same cm/360 in every game?
It's a great starting point. Matching cm/360 keeps your muscle memory consistent, but feel free to tweak it slightly for games that play very differently.
What is a good sensitivity for competitive FPS games?
Most competitive players sit between 20 and 40 cm/360. Lower sensitivity gives more precision, higher sensitivity lets you turn faster, so pick what feels consistent for you.
Does FOV affect mouse sensitivity?
Not your cm/360. Turning 360 degrees takes the same mouse distance at any FOV, but a wider FOV makes small movements feel slower on screen; use the FOV converter to adjust.
Can I convert sensitivity for Fortnite, Marvel Rivals or Call of Duty?
Yes. The main converter supports them, and Overwatch, Valorant, CS2 and Apex also have dedicated conversion pages.
Sources & Methodology
Yaw values used in the sensitivity converter:
- Overwatch: 0.0066 (Source: Blizzard API documentation, verified in-game)
- Valorant: 0.07 (Source: Riot Games sensitivity documentation)
- CS2: 0.022 (Source: Valve developer wiki, unchanged from CS:GO)
- Apex Legends: 0.022 (Source: Respawn, matches Source engine default)
- Fortnite: 0.5555 (Source: Epic Games documentation, scaled to 0-100 range)
- Marvel Rivals: 0.0066 (Source: NetEase, uses Overwatch-style sensitivity)
- Call of Duty: 0.066 (Source: Activision, based on Modern Warfare 2019+)
All calculations use standard 1080p resolution (1920x1080) at 103° horizontal FOV where applicable. For FOV-dependent games, conversion assumes similar FOV settings. Game FOV numbers themselves are on the FOV converter.
