The natural unit for measuring angles is the radian, which is derived from the formula for the
circumference c of a circle: c = 2 π × r, where r is the radius. If r = 1, then c = 2 π, so the
radian is defined such that a circle has 2 π radians. It also has 360 degrees.
1 radian = 360 / 2 π = 180 / π =57.295779513082320876798154814106 degrees
1 degree = 0.017453292519943295769236907684886 radians
1 arcmin = 0.000290888208665722 radians
1 arcsec = 0.00000484813681109536 radians.
