How to convert it

Find your sensitivity in Fortnite. It is in the input settings, where the X-axis sensitivity is shown as a percentage, under X-Axis Sensitivity (%).
Multiply it by 0.2525 (0.005555 ÷ 0.022), or type it into the converter above, and enter the result in Left 4 Dead.
Use the same mouse DPI in both games, with raw input on and mouse acceleration off.
