How to Convert Radian to Milliradian

1 radian = 1000 milliradians

Milliradian = Radian × 1000

Example: 12 rad × 1000 = 500 mrad

Reverse Conversion

To convert milliradians back to radians:

  • Remember, 1 milliradian equals 0.001 radians.
  • To convert 500 mrad to rad, multiply 500 x 0.001, resulting in 12 rad.

12 rad is also equal to:
