Frequently Asked Questions — R6 Siege to Fortnite Conversion
How do you convert Rainbow Six Siege sensitivity to Fortnite (Ballistic & Battle Royale)?
To convert Rainbow Six Siege sensitivity to Fortnite (Ballistic & Battle Royale) at the same mouse DPI, multiply your R6 Siege sensitivity by 0.010314 (or divide by 96.953005). This derives from the exact engine yaw ratio: R6 Siege uses 0.00572958° per mouse count (Ubisoft AnvilNext 2.0), whereas Fortnite uses 0.5555° per mouse count (Unreal Engine 5.5).
What is 1 R6 Siege sensitivity in Fortnite (Ballistic & Battle Royale) at 800 DPI?
At 800 DPI, a R6 Siege sensitivity of 1 equals 0.0103 in Fortnite (Ballistic & Battle Royale). Both settings produce an identical 199.49 cm (78.54 inches) physical 360-degree turn on your mousepad.
Does FOV difference between R6 Siege (84° (Vertical FOV (84°–90° VFOV))) and Fortnite (80° (80° Locked (BR) / 103° (Ballistic FPS))) affect converted sensitivity?
Converting by yaw ratio (0.0103×) locks your 3D 360-degree physical rotation distance (199.5 cm/360°) for consistent gross arm/wrist muscle memory. However, because R6 Siege renders at 84° (Vertical FOV (84°–90° VFOV)) and Fortnite renders at 80° (80° Locked (BR) / 103° (Ballistic FPS)), micro-flicks near the center crosshair may feel slightly faster or slower on screen depending on camera focal length.
