Plane angles have been measured in many different units. The most contemporary units are the degree ( ° ) and radian (rad), but many others have been used throughout history.
The radian (rad) is the SI unit for measuring angles. one radian is just under 57.3 degrees. Accepted prefixes still not accepted in pure math.
A minute of arc, other names is arcminute (arcmin), arc minute, or minute arc is a unit of angular measurement equal to 160 of one degree, one minute of arc is 121600 of a turn.
Divide the minute of arc value by 3437.749237
radian = minute of arc / 3437.749237
Multiply the radian value by 3437.749237
minute of arc = radian x 3437.749237
One radian (rad) is equal to 3437.749237 minute of arc (')
1 radian (rad) = 3437.749237 minute of arc (')
One minute of arc (') is equal to 0.000291 radian (rad)
1 minute of arc (') = 0.000291 radian (rad)
