Black Ops 4 is fast, with quick time-to-kill and busy maps. A medium sensitivity around 22cm to 38cm per 360 lets you react without overshooting.
Use the calculator above. Enter the game you currently play, your in-game sensitivity and your DPI, then choose Call of Duty: Black Ops 4. It keeps your cm/360 the same, so the converted sensitivity feels identical to what you already aim with.
Most players use 400 or 800 DPI and set their in-game sensitivity from there. The DPI itself matters less than your cm/360, the distance you move the mouse for a full turn. Pick 800, set your Call of Duty: Black Ops 4 sensitivity to land in the range above, and leave it alone.
