Set the same sensitivity in Counter-Strike 2 and Valorant and they will feel nothing alike. This is not a preference or a placebo — the two games measure sensitivity on different scales.
Yaw, briefly
Every game has a value called yaw: how far the view turns for one unit of mouse movement. CS2 uses 0.022. Valorant uses 0.07. Overwatch 2 and Call of Duty use 0.0066.
Because the scales differ, the same sensitivity number produces a completely different turn. A lower yaw needs a higher number to feel the same.
The number that does transfer
What your hands actually learned is cm/360 — how far you physically move the mouse to turn a full circle. That distance is the same physical action in every game, which is why it is the thing worth preserving.
The conversion is: new sensitivity = old sensitivity × (old yaw ÷ new yaw)
eDPI, and what it is not
eDPI is sensitivity multiplied by mouse DPI. It compares two players inside the same game usefully. It does not compare across games, because it ignores yaw entirely — the exact thing that differs.
Where conversion stops working
Two popular games cannot be converted exactly.
Fortnite uses a percentage slider whose feel changes with your field of view. There is no single number that matches every FOV setting.
Rainbow Six Siege applies a multiplier from its configuration file. If you have changed it from the default, any conversion will be off by that same ratio.
For both, a converted number is a starting point to adjust from, not an answer.
