Mouse DPI Calibrator
Estimate actual mouse DPI from measured cm/360, in-game sensitivity, and game yaw.
About This Tool
Mouse CPI can differ slightly from the number printed in software. This tool reverse-calculates the DPI implied by your real measured cm/360.
It is helpful for checking whether a new mouse, sensor setting, or surface change altered your effective sensitivity.
