Frequently asked questions

In mathematics and programming. Most trig functions in code (Math.sin, Math.cos) take radians, not degrees. Convert with: radians = degrees × π / 180.

Astronomy and navigation. The Moon's diameter is about 31 arcminutes as seen from Earth. GPS coordinates use decimal degrees, but older maps use degrees, minutes, seconds (DMS).

A gradian (also called gon) divides a right angle into 100 parts, so a full circle = 400 gradians. Used in surveying and some European engineering fields. Rarely encountered elsewhere.
