Mouse sensitivity and FOV converter
Convert sensitivity between games so your aim carries across, and convert field of view.
How it works
Converts mouse sensitivity between games using centimetres per 360-degree turn as the common unit, and converts field of view between the horizontal, vertical and 4:3-referenced conventions.
Centimetres per 360 is the only figure that transfers. A sensitivity value of 2 means nothing across games, because each engine applies its own multiplier to counts from the mouse. The physical distance your hand moves to turn all the way around is the same quantity everywhere, so converting through it is what actually preserves muscle memory.
DPI multiplies with in-game sensitivity, so 800 DPI at sensitivity 2 and 1600 DPI at sensitivity 1 are identical in effect. Very high DPI offers no accuracy benefit on modern sensors and can amplify sensor noise and jitter — most competitive players sit between 400 and 1600.
Field of view has three conventions and mixing them is the usual cause of a "wrong" FOV. Horizontal is most common; vertical is used by Source engine games; and some titles quote horizontal FOV referenced to a 4:3 frame, which reads differently on a widescreen monitor. The conversion depends on aspect ratio, so the tool asks for it.

Common questions
- How do I keep the same sensitivity between games?
- Convert through centimetres per 360-degree turn. Raw sensitivity numbers mean nothing across engines, but the physical hand movement to turn around is comparable everywhere.
- Is higher DPI better?
- No. DPI multiplies with in-game sensitivity, so 800 at sens 2 equals 1600 at sens 1. Very high DPI can amplify sensor noise; most competitive players use 400–1600.
- Why does my FOV look wrong after converting?
- Probably a convention mismatch. Horizontal, vertical and 4:3-referenced horizontal FOV are three different measurements, and the conversion depends on your aspect ratio.
