About this calculator

This tool converts angle measurements between degrees (the 360° circle used in everyday geometry), radians (the unit based on π used throughout calculus, physics and programming), and gradians (the 400-unit system used in some surveying and civil engineering software).

Programmers converting angles for trigonometric functions (which in most languages expect radians, not degrees), surveyors working with equipment calibrated in gradians, and students moving between a math class that uses radians and a physics class that reports results in degrees all use it to avoid an easy-to-make unit mismatch that throws off an entire calculation.
