Moving your aim to another game? Pick the converter for the game you are starting from, enter your current sensitivity and DPI, then choose the game you are moving to. The calculator does the scale conversion so you can start with the same physical mouse movement instead of guessing.
Keep the same DPI when you can. If you are changing DPI too, enter both values in the calculator. Match cm/360 across games rather than copying eDPI, since each game uses its own sensitivity scale.
The converted number can look completely different from your old sensitivity. That is expected. CS2, Valorant, Fortnite and Apex do not use the same scale.
Use cm/360 when you want the same hip-fire mouse travel. eDPI is useful for comparing players in one game, but it does not translate cleanly between games. Field of view, aspect ratio, ADS multipliers and weapon zoom can still make a mathematically matched sensitivity feel different.
If you are tuning a game from scratch, start with the Valorant sensitivity guide, Fortnite sensitivity guide, or CS2 FOV and viewmodel guide.
Match cm/360 across different games. eDPI is DPI multiplied by in-game sensitivity, so it only makes a fair comparison when both players use the same game's scale.
Enter both the current and target DPI. As a quick check, doubling your DPI usually means halving the in-game sensitivity to preserve the same mouse travel.
Hip-fire distance can match closely, but different FOV, ADS rules and camera movement can change the feel. Test the result, then make small adjustments instead of changing everything at once.
