Mouse Sensitivity Converter

Sensitivity is a multiplier that determines how fast your crosshair moves in response to mouse movement. A higher sensitivity means less physical mouse movement is needed to turn, while a lower sensitivity requires more physical movement for the same rotation; its effect on accuracy depends on the player and game. Each game applies this multiplier differently using an internal yaw value, which is why the same sensitivity number feels different across games.

DPI (Dots Per Inch) is the hardware sensitivity of your mouse. It defines how many movement counts your mouse reports for every inch of physical movement. 800 DPI means 800 counts per inch. Higher DPI means the cursor moves further per inch of movement. Most competitive FPS players use between 400 and 1600 DPI, with 800 being the most common. DPI is set in your mouse software and is independent of in-game sensitivity.

eDPI (effective Dots Per Inch) is your DPI multiplied by your in-game sensitivity. It provides a single number to compare sensitivities regardless of DPI setting. For example, 800 DPI at 1.0 sens and 400 DPI at 2.0 sens both yield an eDPI of 800, meaning they produce identical aiming speed. This tool normalizes eDPI to CS2 yaw values for universal comparison across all games.

cm/360 is the distance in centimeters you need to move your mouse to perform a full 360-degree turn in-game. It is the universal standard for comparing sensitivity across different games because it accounts for each game's internal yaw value. Lower cm/360 values mean faster sensitivity (less mouse movement needed), while higher values mean more mouse movement for the same turn. Most CS2 pros use between 30-60 cm/360.

Each FPS game uses a different internal yaw (rotation per mouse count) value, so the same sensitivity number produces completely different aiming speeds between games. Matching cm/360 preserves the physical distance for the same rotation angle, regardless of which game you play. Perceived aiming and adaptation can still differ with field of view, zoom and game mechanics.
