Unit family
Angle
Degrees and radians are often mixed in software, geometry and trigonometry. Formulas usually expect a specific angle unit.
| Unit | Symbol | Formule |
|---|---|---|
| Radian | rad | base |
| Degree | ° | 1° = π/180 rad |
| Gradian | gon | 1 gon = π/200 rad |
| Turn | turn | 1 turn = 2π rad |
| Arcminute | ′ | 1′ = 1/60° |
| Arcsecond | ″ | 1″ = 1/3600° |

Factors come from the stored source family and are not derived from rounded display values.
UnitCloud keeps calculating with stored factors and rounds only the displayed output by selected precision.
Do not use as the sole basis for official, medical, safety-critical or contractual decisions.
