Mouse sensitivity converter
Convert your mouse sensitivity between games so the same physical mouse movement turns the same amount in each.

"Between games" mode uses each game's own fixed engine constant — how many degrees your view turns per raw mouse count — so switching between two supported games keeps the same physical mouse movement mapped to the same on-screen turn. "FOV change" mode is different: it's pure trigonometry for staying consistent within one game when only the field-of-view setting changes, so it needs no per-game constant and never goes stale. "eDPI" mode is the simplest of the three — just DPI multiplied by sensitivity, the standard number competitive players quote to compare setups across games or players.
Currently supports: CS:GO / Counter-Strike 2, Valorant, Overwatch 2, Apex Legends, Fortnite (sensitivity %, not a decimal multiplier). Want a game added? Suggest one.

Worked example
Say you play CS2 at sensitivity 2.5 and want the equivalent in Valorant. In "between games" mode: 2.5 × 0.022 ÷ 0.07 ≈ 0.786 — a much lower number in Valorant, because its yaw constant is larger, so less raw sensitivity produces the same physical turn.
Now say you're staying in CS2 but changing FOV from 90° to 106°. In "FOV change" mode: 2.5 × tan(53°) ÷ tan(45°) ≈ 3.32 — a higher sensitivity number is needed at the wider FOV to keep the same felt turn speed, since a wider view packs more visual angle into the same mouse movement.
For eDPI mode: 800 DPI × 2.5 sensitivity = 2000 eDPI. That single number is what competitive players compare directly — two players with different DPI and sensitivity settings but the same eDPI are moving their view by the same amount for the same physical mouse movement, even without knowing either person's exact DPI.
FAQ
How does the conversion work?
Each game turns your view by a fixed number of degrees per raw mouse count at sensitivity 1.0. Converting keeps that physical-turn-to-screen-turn ratio the same across games, so your aim feels identical.
Do I need to know my mouse DPI?
No — DPI cancels out of the sensitivity conversion itself. It's optional here and only used to also show the physical distance (cm per 360°) your mouse travels, if you want it.
Are these numbers exact?
They're widely cited community/developer-published values for each game's engine, cross-checked against independent sources but not verified against the games directly — treat them as a close starting point, not a guarantee, and use in-game test ranges to fine-tune.
Which games are supported for between-games conversion?
CS:GO/Counter-Strike 2, Valorant, Overwatch 2, Apex Legends, and Fortnite. Call of Duty is deliberately not included — it has too many titles with differing aim-down-sights multipliers for one reliable constant.
What's the difference between the two modes?
"Between games" converts sensitivity from one supported game to another, using each game's engine constant. "FOV change" converts sensitivity within a single game when only its field-of-view setting changes — pure trigonometry, no per-game constant involved.
Why doesn't the FOV mode need a specific game?
It's based purely on the trigonometric relationship between old and new field-of-view angles, which is the same regardless of which game you're in — unlike the between-games mode, which relies on each game's own engine constant.
What if my mouse DPI isn't listed as a supported value?
DPI isn't matched against a list — you can enter any value. It's optional and only used to additionally show cm-per-360°; the sensitivity conversion itself doesn't need it at all.
Can I convert sensitivity for a game not in the list?
Not with the between-games mode — it only works with the specific games listed. Use the "Suggest one" link on this page if you'd like a game added.
Does this calculator work with controllers?
No — it's built around mouse sensitivity (yaw per raw mouse count), which is a different kind of input than controller stick sensitivity curves.
What is eDPI?
Effective DPI — mouse DPI multiplied by in-game sensitivity. It's the standard single number competitive players quote to compare setups across games or players, since raw sensitivity alone doesn't mean much without knowing the DPI it's paired with.
Is DPI optional in eDPI mode, like the other modes?
No — in eDPI mode, DPI is required, since eDPI is defined as DPI × sensitivity. That's different from "between games" mode, where DPI is optional and only used to additionally show cm-per-360°.
Does eDPI mode need to know which game I'm playing?
No — like the FOV mode, eDPI is pure arithmetic (DPI × sensitivity) with no per-game engine constant involved, so it works the same for any game.
