Angles come in many units. Engineers and programmers work in radians, surveyors and navigators use degrees, and astronomy uses arcminutes and arcseconds for the tiniest fractions of a circle. Converting between them by hand involves awkward constants that are easy to misremember.
This angle converter does the work for you. Type any value, choose its unit, and every other common angle unit is shown instantly — including gradians and full turns, which are handy for compass bearings and rotational mechanics.
How many degrees in a radian? One radian ≈ 57.2958 degrees (180/π).
What is a gradian? A gradian is 1/400 of a turn, so 100 gradians equal a right angle.
