It is mouse DPI times in-game sensitivity. With 800 DPI and sensitivity 1.5, eDPI is 1200. It compares setups inside the same game, but not across different games.

Calculate mouse eDPI and cm/360, convert sensitivity between games and compare two setups.
eDPI (effective DPI) is your mouse DPI multiplied by the in-game sensitivity. It sums up a setup in one number, but it only compares fairly inside the same game, because every game turns mouse movement into degrees in its own way. The measure that works across games is cm/360: how many centimeters the mouse travels for the camera to make a full turn, computed as (2.54 × 360) ÷ (DPI × sensitivity × yaw). Yaw is how many degrees the camera turns per mouse count at sensitivity 1. This tool reuses the values from the sensitivity converter (0.022 for the Source and Quake family, 0.07 for Valorant and 0.0066 for Overwatch) and includes only linear-model games, so the result is exact. Besides the direct calculation, Inverse mode shows the sensitivity in each game for a target cm/360, and Compare mode puts two setups side by side with the percentage difference in speed.
