Frequently asked questions

How do I convert degrees to radians?

Multiply degrees by π/180 (≈0.0174533). So 180° = π radians ≈ 3.14159 radians.

What is a gradian?

A gradian (or gon) divides a right angle into 100 units, so a full circle is 400 gradians.

How many arcminutes in a degree?

1 degree = 60 arcminutes = 3,600 arcseconds.
