Angle Radian Converter
Convert between degrees, radians, and grads, with DMS support.
Degree ↔ Radian ↔ Grad
DMS (Degree-Minute-Second) Conversion
Common Angle Reference
| Degree | Radian | Grad |
|---|---|---|
| 0° | 0 | 0 |
| 30° | π/6 | 33.33 |
| 45° | π/4 | 50 |
| 60° | π/3 | 66.67 |
| 90° | π/2 | 100 |
| 120° | 2π/3 | 133.33 |
| 180° | π | 200 |
| 270° | 3π/2 | 300 |
| 360° | 2π | 400 |
Conversion Relationships
- 1 radian = 180/π ≈ 57.2958°
- 1° = π/180 ≈ 0.01745 rad
- 1 grad = 0.9°, 1° = 10/9 grad
- Full circle: 360° = 2π rad = 400 grad
Usage Instructions
Features
Real-time conversion between degree (°), radian (rad), and grad units, supporting bidirectional conversion between decimal degrees and DMS format, with a common angle reference table.
Steps
Enter a value in any unit input field and other units will auto-convert → In the DMS area, enter decimal degree or D/M/S for conversion → Click any row in the reference table to apply that angle.
Notes
All conversions run locally in real time without uploading data; radian results keep high-precision decimals with trailing zeros automatically removed; DMS conversion keeps two decimal places for seconds.
