Formula
CS2 sensitivity = Valorant sensitivity × (0.07 ÷ 0.022) × (source DPI ÷ target DPI)
Example: at 800 DPI in both games, 0.32 × 0.07 ÷ 0.022 = 1.01818 in CS2. Both are modeled at about 51.03 cm/360. If the target mouse DPI changes, the converter applies the DPI ratio too.
Why does eDPI change?
At 800 DPI, Valorant 0.32 is 256 eDPI, whereas CS2 1.01818 is about 814.55 eDPI. This difference does not mean the physical turn is faster. The two games use different yaw scaling constants.
What about ADS and FOV?
Matching physical full-turn distance is only a baseline. Different field of view, zoom, scoped sensitivity and in-game input handling can make aiming feel different. Check the match inside both games.
