Enter the angle, choose degrees as the from unit and radians as the to unit. One degree equals pi divided by 180 radians, which is about 0.01745.
One radian is about 57.2958 degrees, because a full circle of 360 degrees equals two pi radians.
A gradian, also called a gon, divides a right angle into 100 equal parts, so a full turn is 400 gradians. It is used in surveying.
One turn, or revolution, is a complete circle. It equals 360 degrees, two pi radians or 400 gradians.
One degree contains 60 arcminutes and each arcminute contains 60 arcseconds. Astronomers and navigators use them for very small angles.
It rewrites the angle in the traditional format, so 12.5 degrees becomes 12 degrees 30 minutes 0 seconds.
