Rainbow Six Siege to Fortnite Sensitivity Converter

How Rainbow Six Siege to Fortnite sensitivity conversion works

Fortnite and Siege both show relatively large numbers, but their labels and underlying scales differ. Use Fortnite’s displayed X-Axis percentage and Siege’s horizontal slider with the default multiplier; do not transfer targeting or ADS percentages.

At equal DPI, multiply your Rainbow Six Siege setting by 1.03143. To reverse the conversion, divide by that factor. The number changes because the two games interpret sensitivity units differently; the distance travelled by your mouse is the quantity being matched.

Target sens = source sens × 1.03143 × source DPI ÷ target DPI

For example, 10 in Rainbow Six Siege at 800 DPI becomes approximately 10.31428 in Fortnite at 800 DPI. Both describe 19.95 cm for one complete horizontal turn before rounding. Keep the unrounded value in the tool if you plan to swap directions again.

The first two rows keep the source setup fixed and change only the target DPI. The third changes source sensitivity. This separates a hardware-DPI change from an in-game sensitivity change, which is useful when comparing two saved configurations.

Settings to check in each game

Rainbow Six Siege

Options > Controls > Mouse Sensitivity Horizontal

These examples assume MouseSensitivityMultiplierUnit=0.02. A downloaded config or an old personal tweak may change that value. For a target Siege result, multiply the default result by 0.02 divided by your custom multiplier. For a source Siege value, first normalize it by multiplying by your custom multiplier divided by 0.02.

Fortnite

Settings > Mouse and Keyboard > X-Axis Sensitivity (shown as a percentage)

Enter the displayed X-Axis percentage. A menu value of 6.5% means 6.5 in this converter, not 0.065. This factor-of-100 input mistake is much larger than any rounding difference. Y-Axis, Targeting, Scope, Building and Editing settings remain separate; this page does not claim one horizontal number sets all of them.

FOV and ADS: why these games can still feel different

A full-turn match does not promise equal movement across the screen. A different field of view, aspect ratio or camera perspective can alter the apparent speed of a target. Compare the same physical mouse travel first, then decide whether a different visual feel needs a personal adjustment.

Rainbow Six Siege and Fortnite also keep some aiming controls separate from their base horizontal setting. This tool does not calculate a monitor-distance match, a scoped multiplier, controller aim or vertical sensitivity. Apply the result to the named setting, then evaluate those other controls independently.

To verify the transfer, mark a starting point on the mousepad and move horizontally until the camera completes a turn. Repeat in both games with acceleration and game-specific modifiers accounted for. If space is limited, compare half-turns using half the reported cm/360 distance. Menu rounding can cause a small mismatch; a large mismatch calls for checking DPI, the input unit and game settings.
