Returns a Unit object representing angle in degrees (Id = 9102). A degree is equal to pi/180 radians.

Returns a Unit object representing angle in gons (Id = 9106). Equivalent to one one-hundredth of a right-angle, a gon is equal to pi/200 radians. Also known as a grad.

Returns a Unit object representing angle in grads (Id = 9105). Equivalent to one one-hundredth of a right-angle, a grad is equal to pi/200 radians. Also known as a gon.

Returns a Unit object representing angle in microradians (Id = 9109). One microradian is equal to one millionth of a radian.

Returns a Unit object representing angle in mils (Id = 9114). One mil equals the angle subtended by 1/64000 part of a circle, approximately 1/1000th of a radian. This unit is commonly used by military organizations.

Returns a Unit object representing angle in arc-minutes (Id = 9103). An arc-minute is equal to 1/60th of a degree.

Returns a Unit object representing angle in centesimal minutes (Id = 9112). A centesimal minute is equal to 1/100th of a grad or gon.

Returns a Unit object representing angle in radians (Id = 9101). A radian is an SI standard unit, equaling 180/pi degrees.

Returns a Unit object representing angle in arc-seconds (Id = 9104). An arc-second is equal to 1/60th of an arc-minute.

Returns a Unit object representing angle in centesimal seconds (Id = 9113). A centesimal second is equal to 1/100th of a centesimal minute.
