What is an Angle Converter?

An angle converter is an online tool that translates angle values between different measurement systems. Angles can be expressed in multiple units depending on the field of use:

  • Degrees (°) — the most common unit used in everyday geometry and navigation
  • Radians (rad) — the standard unit used in mathematics and physics
  • Gradians (grad) — used in surveying and some European engineering fields
  • Turns — expressing a full rotation as a single unit, used in some programming contexts

Supported Angle Units

  • Degrees (°)
  • Radians (rad)
  • Gradians (grad)
  • Turns

Common Angle Conversion Examples

  • 360 Degrees = 2π Radians = 400 Gradians = 1 Turn
  • 90 Degrees = π/2 Radians = 100 Gradians = 0.25 Turns
  • 180 Degrees = π Radians = 200 Gradians = 0.5 Turns

Frequently Asked Questions


Degrees divide a full circle into 360 equal parts, while radians measure angles based on the radius of a circle. One full circle equals 2π radians. Radians are the standard unit in mathematics and physics.

To convert degrees to radians, multiply the degree value by π/180. For example, 90 degrees equals 90 × (π/180) = π/2 radians, approximately 1.5708.

Gradians divide a full circle into 400 equal parts. They are primarily used in surveying, civil engineering, and military navigation in some European countries.
