Angle Converter
Convert between angle units: degrees, radians, gradians.
Angle Converter
Convert between different units for measuring angles used in mathematics, engineering, and navigation.
Angle Units
- Degree (°): 360° = full rotation
- Radian (rad): 2π radians = full rotation, SI unit
- Gradian (grad): 400 gradians = full rotation
Angle Conversion Example
A right angle is 90°. Convert to radians:
- Result: 90° = π/2 radians ≈ 1.571 radians
Frequently Asked Questions
-
A radian is the angle formed when the arc length equals the radius. 2π radians = 360°.
-
Radians are the natural unit for circular motion and calculus, making formulas simpler.
-
A gradian (grade) is used in surveying and some European countries. 1 gradian = 0.9 degrees.
