Gaming tools to boost your performance
Everything you need to optimize your gaming setup in one place. Sensitivity and eDPI calculators, mouse and keyboard tests, reaction and speed tests. Free, no sign-up, in your language.
Sensitivity & eDPI Calculators
Transfer your aim settings between titles, analyze your effective DPI and fine-tune your setup to the millimeter.
Mouse Tests: CPS & Diagnostics
Full peripheral diagnosis: click speed, double-click response and the state of every button.
Keyboard Tests: KPS & Ghosting
Evaluate your keypress speed, check each key is working and analyze simultaneous key response.
Reaction & APM Tests
Test your response capability and hand-eye coordination with timed exercises.
Key sensitivity concepts
What is Yaw?
Yaw is the internal value each game uses to translate your sensitivity into actual mouse movement. It is the number of degrees your character rotates per unit of mouse movement. Every game has its own yaw: CS2 uses 0.022, Valorant uses 0.07. That is why the same sensitivity feels different across games. Our calculator uses these values to perform the exact conversion.
What is eDPI?
eDPI (effective DPI) is your in-game sensitivity multiplied by your mouse DPI. For example, sensitivity 2 with 800 DPI = 1600 eDPI. It is the universal way to compare sensitivities between players, because two players with the same eDPI move exactly the same — regardless of whether one uses 400 DPI with sensitivity 4 and the other uses 800 DPI with sensitivity 2.
What is cm/360?
cm/360 tells you how many centimeters you need to move your mouse to make a full 360-degree turn in-game. It is the most intuitive measure of sensitivity: a cm/360 of 30 cm means you need to move your mouse 30 centimeters to complete a full rotation. CS2 pro players typically use between 30 and 50 cm/360.
Convert your sensitivity between games in seconds
When you switch games, keeping the same mouse sensitivity is key to preserving your muscle memory. But every game uses a different system: what is 0.5 in Valorant is 1.59 in CS2 and 5.3 in Overwatch 2. Our calculator does the conversion for you — free, accurate and instant. All you need is your current sensitivity, your DPI and the game you want to convert to.
