CS2 Sensitivity Explained
Sens, DPI, eDPI, cm/360 — four numbers that all describe the same thing: how far your aim moves. Here's how they fit together.
The four numbers
- DPI — dots per inch, set on your mouse. It's how many counts the mouse reports per inch of physical movement.
- In-game sensitivity — the multiplier you set in CS2's options. On its own it means little without knowing your DPI.
- eDPI — effective DPI, calculated as
DPI × sensitivity. It's the fairest single number for comparing two players' aim speed. - cm/360 — the centimetres of mouse movement needed for a full 360° turn. This is the real-world measure of your aim.
How they relate
DPI and sensitivity multiply together to give eDPI. A higher eDPI means a faster, twitchier aim; a lower eDPI means more arm movement and, for many players, more precision. cm/360 is simply eDPI expressed as physical distance — lower eDPI gives a larger cm/360, because you move the mouse further for the same turn.
That's why 400 DPI at 2.0 sens and 800 DPI at 1.0 sens feel identical: both land on an eDPI of 800 and the same cm/360.
Why converting preserves muscle memory
- Your aim is trained on a specific physical distance per turn — your cm/360.
- Different games rotate by different amounts per mouse count (their "yaw"), so the same sensitivity number means different things in different games.
- A proper conversion adjusts the sensitivity so cm/360 stays constant, keeping your hand movements exactly the same.
Skip the conversion and you're effectively relearning your aim from zero. Convert correctly and the reps you've already banked carry straight across.
