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.
An angular mil or mil is a unit of plane angle, 1 Angular Mils (µ mil) is equal to 0.000981748 radians, while 1 Milliradian is equal to 0.001 radians.
Divide the mil value by 1018.591329
radian = mil / 1018.591329
Multiply the radian value by 1018.591329
mil = radian x 1018.591329
One radian (rad) is equal to 1018.591329 mil (µ)
1 radian (rad) = 1018.591329 mil (µ)
One mil (µ) is equal to 0.000982 radian (rad)
1 mil (µ) = 0.000982 radian (rad)
