eDPI vs cm/360: Understanding Aim Metrics
Learn the crucial differences between game-specific effective DPI (eDPI) and universal physical turn distance (cm/360) to maintain consistent crosshair muscle memory across all titles.
1. What Are eDPI and cm/360?
Gamers track their aiming speed using two standard metrics:
Effective DPI (eDPI)
A simple product of your mouse hardware DPI and in-game sensitivity (eDPI = DPI × Sens).
Centimeters per 360°
The exact real-world physical distance in centimeters your hand must travel on the mousepad to complete a full 360° camera rotation.
2. When eDPI Works Best
eDPI is the fastest and easiest metric when discussing settings with other players within the exact same game. If a teammate in Counter-Strike 2 mentions they use 800 eDPI, you immediately know their aim speed whether they play on 400, 800, or 1600 DPI.
3. The Major Limitation of eDPI Across Games
eDPI is mathematically tied to the specific game's internal rotation scale (yaw constant). Because each game engine calculates rotation differently, eDPI cannot be transferred across different games:
51.95 cm / 360° (Tactical Arm Aim).16.33 cm / 360° (Over 3× faster wrist aim!).4. Why cm/360 Is the Universal Standard
Physical distance (cm/360) is the only true universal standard. If your physical sensitivity is 35 cm / 360°, entering the matching in-game sensitivity sliders in CS2, Valorant, Apex Legends, and Overwatch 2 guarantees that a 10 cm hand swipe moves your crosshair the exact same angle across every game.
5. Direct Comparison Table
| Metric | eDPI (Effective DPI) | cm/360 (Centimeters per 360°) |
|---|---|---|
| Calculation Formula | DPI × In-Game Sensitivity | [360° ÷ (DPI × Sens × Yaw)] × 2.54 |
| Scope | Single game title only | Universal across all 3D game engines |
| Units | Abstract numerical index | Real-world physical metric units (cm) |
| Hardware Agnostic? | Yes (same within game) | Yes (across all mice & games) |
| Cross-Game Comparison | Invalid (different yaw factors) | 100% accurate 1:1 muscle memory match |
