Frequently Asked Questions — Fortnite to R6 Siege Conversion
How do you convert Fortnite (Ballistic & Battle Royale) sensitivity to Rainbow Six Siege?
To convert Fortnite (Ballistic & Battle Royale) sensitivity to Rainbow Six Siege at the same mouse DPI, multiply your Fortnite sensitivity by 96.953005 (or divide by 0.010314). This derives from the exact engine yaw ratio: Fortnite uses 0.5555° per mouse count (Unreal Engine 5.5), whereas R6 Siege uses 0.00572958° per mouse count (Ubisoft AnvilNext 2.0).
What is 6.4 Fortnite sensitivity in Rainbow Six Siege at 800 DPI?
At 800 DPI, a Fortnite sensitivity of 6.4 equals 620.4992 in Rainbow Six Siege. Both settings produce an identical 0.32 cm (0.13 inches) physical 360-degree turn on your mousepad.
Does FOV difference between Fortnite (80° (80° Locked (BR) / 103° (Ballistic FPS))) and R6 Siege (84° (Vertical FOV (84°–90° VFOV))) affect converted sensitivity?
Converting by yaw ratio (96.9530×) locks your 3D 360-degree physical rotation distance (0.3 cm/360°) for consistent gross arm/wrist muscle memory. However, because Fortnite renders at 80° (80° Locked (BR) / 103° (Ballistic FPS)) and R6 Siege renders at 84° (Vertical FOV (84°–90° VFOV)), micro-flicks near the center crosshair may feel slightly faster or slower on screen depending on camera focal length.
