Understanding Angle Conversion
Angles measure rotation or the space between two intersecting lines. Degrees are most intuitive, while radians are essential in mathematics and physics. A full circle equals 360° or 2π radians.
| Unit Type | Unit Name | Value in Degrees (°) / Radians (rad) |
|---|---|---|
| Common | Degree (°) | 1° = 0.0174533 rad |
| Common | Radian (rad) | 1 rad = 57.2958° |
| Subdivision | Minute (arcminute) | 1' = 1/60° |
| Subdivision | Second (arcsecond) | 1" = 1/3600° |
| Alternative | Gradian (grad) | 1 grad = 0.9° |
| Reference | Right Angle | 90° = π/2 rad |
| Reference | Straight Angle | 180° = π rad |
| Reference | Full Circle | 360° = 2π rad |
