Quick Reference

1° = π/180 rad ≈ 0.01745 rad

1 rad = 180/π ≈ 57.2958°

1 grad = 0.9° = π/200 rad

1′ = 1/60° = 0.01667°

1″ = 1/3600° = 0.000278°

Frequently Asked Questions

How accurate is the conversion?

Our converter uses exact conversion factors based on mathematical constants (π = 3.14159265358979...). Results are accurate to 10 decimal places for all supported units.

Can I convert from any unit to any other unit?

Yes! You can convert between any two angle units — degrees to radians, radians to gradians, arcminutes to degrees, or within the same system.

What is the difference between radians and degrees?

Degrees and radians are both units of angle measurement. A full circle is 360° or 2π radians (≈ 6.283 radians). Radians are the preferred unit in mathematics and physics because they simplify many formulas.

Is my data private?

Absolutely. All conversions happen entirely in your browser. No data is ever sent to our servers or stored anywhere.
