Angle Conversion Formulas
Our calculator uses these precise angle conversion formulas:
Degrees to Radians: radians = degrees × (π/180)
Radians to Degrees: degrees = radians × (180/π)
Degrees to Gradians: gradians = degrees × (10/9)
Gradians to Degrees: degrees = gradians × (9/10)
Radians to Gradians: gradians = radians × (200/π)
Gradians to Radians: radians = gradians × (π/200)
Common Angle Conversion Examples
| Angle | Degrees | Radians | Gradians |
|---|---|---|---|
| Full Circle | 360° | 2π rad | 400 gon |
| Right Angle | 90° | π/2 rad | 100 gon |
| Straight Angle | 180° | π rad | 200 gon |
| Acute Angle | 45° | π/4 rad | 50 gon |
