Effective DPI (mouse DPI × in-game sensitivity), cm/360° conversion, and cross-game sensitivity matching — with fully editable game profiles instead of hardcoded, outdated constants.

Keep the same physical cm/360° when switching games — the number that actually matters for muscle memory.
Effective DPI (eDPI) is your mouse DPI multiplied by your in-game sensitivity setting. It condenses two separate numbers into one that reflects how fast your cursor or crosshair actually moves — two players with completely different DPI and sensitivity values can land on the exact same eDPI, and their aim will feel identical in terms of raw speed.
While eDPI is useful for comparing raw speed, cm/360° measures something more concrete: how far your mouse physically travels across the mousepad to spin a full 360 degrees in-game. This is the number competitive players rely on for muscle memory, because it stays consistent even when moving between games that scale sensitivity completely differently under the hood.
Every game engine defines "yaw" — how many degrees the camera turns per mouse count at sensitivity 1.0 — using its own internal formula. That's why identical DPI and sensitivity numbers produce a noticeably different turn speed in, say, Valorant versus CS2. This calculator ships with community-sourced yaw values for common titles, but includes an editable override, since yaw can shift after game updates or vary slightly by season — measuring your own via a turn test and entering it here keeps the numbers accurate for you specifically.
The sensitivity matcher below solves a common problem: keeping your physical aim consistent when you pick up a new game. Enter your current setup's game, DPI, and sensitivity, choose the game you're switching to along with its DPI, and the calculator solves for the sensitivity value that preserves your exact cm/360° — so your hand doesn't have to relearn a new turn speed from scratch.
What is eDPI? eDPI, or effective DPI, is your mouse DPI multiplied by your in-game sensitivity setting. It gives a single number that reflects your true cursor speed, since two people with different DPI and sensitivity values can still end up with the same effective speed.
What does cm/360 mean? cm/360 is the physical distance your mouse needs to travel across the mousepad to turn a full 360 degrees in-game. It's considered the most reliable number for muscle memory, since it stays consistent even when switching between games with different sensitivity scaling.
What is yaw and why does it vary by game? Yaw is how many degrees the in-game view rotates per mouse count at a sensitivity of 1.0. Each game engine defines this value differently, which is why the same DPI and sensitivity number produces a different actual turn speed from one game to another.
Why does this calculator let me edit the yaw value? Community-sourced yaw values can drift out of date after game updates, and some titles have per-season adjustments. Editing the yaw constant lets the calculator stay accurate even if a value changes or if you've measured your own through a turn test.
Is this eDPI calculator free to use? Yes, it is completely free with no account or sign-up required, and runs instantly in your browser.
Does this store or upload my sensitivity settings? No — everything is calculated and held only in this page's memory while it's open. Nothing is sent to any server, and the compare table clears when you leave the page.
Note: Yaw values are community-sourced reference constants and may vary slightly by game version or patch. For competitive use, consider verifying with an in-game turn test before relying on the exact numbers here.
