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