Mouse DPI Sensitivity Converter
Convert your mouse sensitivity between different DPI settings while keeping the same effective sensitivity.
Essential for gamers switching mice.
What is DPI?
DPI stands for Dots Per Inch — the number of distinct positions a mouse sensor registers per inch of physical movement. A higher DPI means the cursor moves farther on screen for the same physical movement. A lower DPI means slower, more controlled movement.
DPI vs in-game sensitivity
DPI is a hardware setting (set via mouse software or physical button). In-game sensitivity is a software multiplier applied on top. The two combine to determine your effective sensitivity — how far your character’s view rotates per inch of mouse movement.
Effective Sensitivity = DPI × In-Game Multiplier
The conversion formula
When switching to a different DPI, you can maintain the exact same feel by adjusting your in-game sensitivity using this formula:
New Sensitivity = Old Sensitivity × (Old DPI ÷ New DPI)
For example: if you play at 800 DPI with sensitivity 3.0, switching to 400 DPI requires a sensitivity of 6.0 to feel identical (400 DPI × 6.0 = 2,400 = 800 DPI × 3.0 = 2,400).
cm per 360° rotation
A more useful measure than raw sensitivity is how many centimetres of mouse movement produce a full 360° rotation in-game. This figure is completely DPI and game-agnostic and lets you compare sensitivity between games and players:
cm/360 = 2.54 × 360 / (DPI × In-Game Sensitivity × Yaw)
Most FPS games use a yaw value of 0.022 (the Quake/Source engine standard).
What DPI is best?
Most competitive FPS players use 400–1600 DPI with relatively low in-game sensitivity. Lower DPI requires more physical mouse movement per action, which many players find gives better control and consistency. However, the best setting is the one you are most comfortable with.
