Overwatch 2 to Marathon Sensitivity Converter

How Overwatch 2 to Marathon sensitivity conversion works

Marathon uses half Overwatch 2’s yaw scale, so its numeric setting is twice the Overwatch number at equal DPI. That exact relationship still meets Marathon’s whole-number menu limitation; compare rounding before blaming the conversion.

At equal DPI, multiply your Overwatch 2 setting by 2. 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 × 2 × source DPI ÷ target DPI

For example, 5 in Overwatch 2 at 800 DPI becomes approximately 10 in Marathon at 800 DPI. Both describe 34.64 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

Overwatch 2

Options > Controls > General > Mouse > Sensitivity

Use the base mouse sensitivity and check whether the selected hero overrides it. The 0.0066 scale is numerically finer than Valorant or CS2, so compare physical distance rather than the size of the setting. Scoped hero controls are independent from the hipfire conversion.

Marathon

Settings > Keyboard / Mouse > Look Sensitivity

Use Look Sensitivity, not ADS Sensitivity Modifier. The catalog records a 0.0033 scale and whole-number Look Sensitivity, based on the sources and date shown above. An exact output with several decimals is a mathematical target; the nearest menu number is what you can actually test.

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.

Overwatch 2 and Marathon 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.
