Angle Converter
Convert degrees, radians, gradians, turns, arcminutes and arcseconds.
About this converter
A full turn is 360 degrees, 2π radians or 400 gradians. Arcminutes and arcseconds divide a degree by 60 and by 3,600. Degrees are used for compass bearings, maps and everyday geometry. Radians are the natural unit in mathematics and programming: most calculators in radian mode and the sine and cosine functions of programming languages expect radians, so 90° must be entered as about 1.5708. Gradians, where a right angle is 100, appear on some surveying instruments, and turns are handy for rotations in animation and engineering. Latitude and longitude are often written in degrees, minutes and seconds.
Common degrees to radians conversions
To convert degrees to radians, multiply by 0.0174533. To go back, divide by the same number (or multiply by 57.2958).
