Angle calculator - result

The Angle Calculator allows conversions of the angles entered in degrees, minutes, seconds to the decimal number, radians back and forth. It is also possible to evaluate simple numerical operations - an addition of angles, subtracting angles, angle normalization to interval <0,360°> or <-180°,180°>, etc. Degrees (°), minutes ('), seconds (") to decimal degrees angle converter and back. Enter angle in degrees, minutes, seconds and press the Convert button. Angle units - do not mix with time seconds, minutes or temperature degrees Celsius or °F.

Result:

55.5 = 55.5° = 55°30' = 0.96866 rad = 111/2 π rad = 61.66667 grad = 0.15417 turns


Basic knowledge of angle units

The basic definition is that the full angle is 1 rotation (one turn) = 360° (degrees) = 2π radians = 400 grads (gons). One degree is 60 minutes and one angle minute is 60 seconds.
