Turn (revolution) quick reference
| Turn (revolution) | Degree | Radian | Milliradian |
|---|---|---|---|
| 1 rev | = 360 ° | ≈ 6.283185307 rad | ≈ 6283.185307 mrad |
| 10 rev | = 3600 ° | ≈ 62.83185307 rad | ≈ 62831.85307 mrad |
| 100 rev | = 36000 ° | ≈ 628.3185307 rad | ≈ 628318.5307 mrad |
| 1000 rev | = 360000 ° | ≈ 6283.185307 rad | ≈ 6283185.307 mrad |
