Mouse DPI Calculator

Convert sensitivity between DPI values and calculate eDPI with clear formulas.

Why results may vary

Browsers cannot automatically detect physical mouse DPI, so values must be entered manually.

How to use this test

Enter your current DPI and in-game sensitivity, then enter the new DPI you want to use. The calculator shows the equivalent sensitivity that preserves the same eDPI.

How the measurement works

eDPI is calculated as DPI multiplied by sensitivity. Equivalent sensitivity preserves that product: current DPI × current sensitivity = new DPI × new sensitivity.

How to interpret results

Matching eDPI is a useful mathematical starting point when changing DPI in the same game or sensitivity scale. It does not automatically account for different games, FOV, acceleration or sensitivity formulas.

Troubleshooting tips

Confirm the DPI value in your mouse software and use the game's exact numeric sensitivity. If converting between different games, use a game-specific converter rather than assuming identical sensitivity scales.

QUESTIONS & FIXES

How do I convert sensitivity when changing mouse DPI?

To preserve the same basic eDPI within a compatible game scale, multiply the old DPI by the old sensitivity, then divide by the new DPI to get the new sensitivity. Game-specific FOV and sensitivity formulas can still change perceived feel.

What does cm/360 mean?

cm/360 is the physical mouse distance required to rotate a full 360 degrees in a game. It is useful because it describes the physical feel of sensitivity rather than only software sensitivity numbers.

Does field of view change how sensitivity feels?

Yes. Even when turn distance remains mathematically consistent, different field-of-view settings can change perceived screen motion and make the same sensitivity feel faster or slower.

Can the browser detect my mouse DPI automatically?

No. Physical mouse DPI is not exposed as a reliable browser API, so enter the value from your mouse software or hardware settings.
