In Fortnite, as with most Battle Royale style games, we recommend a medium sensitivity to allow flexibility between close range combat requiring fast tracking and turns, and long range precision. Something in the 25-37cm per 360 turn range is normally recommended.

Use the calculator above. Enter the game you currently play, your in-game sensitivity and your DPI, then choose Fortnite. 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 Fortnite sensitivity to land in the range above, and leave it alone.
