Sensitivity Converter

Mathematical Foundation of Sensitivity Conversion

Game engines utilize different Yaw and Pitch coefficients to map physical mouse delta counts (counts per inch emitted by your sensor) to camera rotation angles. In Counter-Strike 2 (Source Engine) and Apex Legends, the standard Yaw value is 0.022 degrees per count. In Valorant (Unreal Engine 4), Riot Games configured the default Yaw multiplier to 0.07 degrees per count.

By dividing the Source engine Yaw (0.022) by the Valorant Yaw (0.07), we derive the exact mathematical conversion constant:

Therefore, dividing your CS2 or Apex Legends sensitivity by 3.1818 translates your muscle memory perfectly to Valorant, retaining exact 360-degree rotation distance.

Field of View (FOV) Scaling & Focal Length Matching

While exact 360-degree physical rotation distance can be matched mathematically between games, player perception is also affected by Field of View (FOV). Valorant locks the horizontal FOV to 103 degrees (on 16:9 displays). In games like Overwatch 2 (103° FOV default) or Rainbow Six Siege, focal length scaling varies. Matching your cm/360 ensures consistent arm muscle memory across all tactical shooters regardless of visual FOV compression.

Effective DPI (eDPI) & Sensor Polling Frequency

eDPI (Effective Dots Per Inch) is calculated as Mouse Hardware DPI × In-Game Sensitivity. It serves as a unified benchmark to compare physical mouse travel across different hardware configurations. For instance, a player using 400 DPI with 0.70 sensitivity and a player using 1600 DPI with 0.175 sensitivity both operate at an identical 280 eDPI. However, the 1600 DPI configuration yields significantly lower input latency and smoother micro-adjustments due to higher sensor sample density.
