Summary

Convert any angle from radians to degrees instantly using the formula degrees = radians × 180/π, with a reference table of common angles.

How it works

  1. Enter an angle in radians in the input field (plain decimal such as 1.5708).
  2. The converter applies the formula: degrees = radians × (180 / π).
  3. The result is shown as a decimal degree value rounded to six significant figures.
  4. A step-by-step breakdown displays the calculation so you can verify it.
  5. Use the reference table to look up common radian–degree pairs instantly.
  6. Click any row in the reference table to load that angle into the converter.

Use cases

  • Converting radian angles returned by math or physics libraries into readable degrees.
  • Checking degree values when studying trigonometry or calculus.
  • Interpreting rotation results from canvas, SVG, or WebGL transforms.
  • Looking up common angle equivalents such as π/2, π, and 3π/2.
  • Verifying manual calculations of degree values from π-based expressions.
  • Teaching or learning the relationship between radians and degrees.
