eDPI Calculator
eDPI = DPI × in-game sensitivity. cm/360 uses Source-style yaw (default 0.022) — adjust yaw for other engines.

How to use
- Enter your mouse DPI.
- Enter your in-game sensitivity.
- Adjust yaw (radians per count) if your title uses a different m_yaw than the default Source-style 0.022 — check game docs or config.
- Read eDPI and cm/360° from the outputs.
- When comparing with friends, align yaw first; cm/360 is only comparable when yaw matches.
FAQ
What is eDPI?
eDPI is effective DPI, calculated as DPI multiplied by in-game sensitivity.
What is cm/360?
cm/360 estimates how many centimeters of mouse movement are needed for a full 360-degree turn.
Introduction
eDPI Calculator computes eDPI = DPI × in-game sensitivity and estimates cm per 360° turn using a configurable yaw value — common for competitive FPS sensitivity setup.
Purpose
- Translate “feel” between DPI and sens while keeping the same effective sensitivity.
- Share comparable numbers using eDPI or cm/360 when yaw is agreed.
Key Features
- Instant eDPI from DPI × in-game sensitivity.
- cm/360° estimate with configurable yaw (Source-style default for FPS players).
- Pure math — no uploads.
Common Use Cases
- Converting sensitivity when copying a friend’s settings.
- Turning DPI changes into “how many cm for a 360°” for desk sizing.
Best Practices
- Set yaw to match your game engine or cm/360 will be wrong across titles.
- Treat cm/360 as a practical estimate — in-game FOV and acceleration layers still change feel.
Comparison metrics
| Metric | When to compare |
|---|---|
| eDPI | Rough cross-player comparison when everyone uses the same yaw model (or accepts approximation). |
| cm/360° | Best practical analog for desk space — same cm/360 usually feels closest for turning, within the model’s limits. |
Note: cm/360 depends on yaw. Comparing two games with different yaw without adjusting the field invalidates the comparison.
