This converter allows you to convert radians [rad] to milliradians [mrad] or milliradians [mrad] to radians [rad]. Calculations are performed in both directions. The calculation result and the entered value are displayed with up to 20 decimal places for maximum accuracy.

1 radian [rad] = 1,000 milliradians [mrad]1 milliradian [mrad] = 0.001 radians [rad]

Convert radians to milliradians

There are two simple ways to convert radians [rad] to milliradians [mrad]. In the first calculation method, the value in radians [rad] is divided by 0.001. The second method multiplies the value in radians [rad] by 1,000.

  • Milliradians [mrad] = radians [rad] ÷ 0.001
  • Milliradians [mrad] = radians [rad] * 1,000

Convert milliradians to radians

Converting milliradians [mrad] to radians [rad] is easy and can be done in two ways. The first method involves multiplication, whereby the value in milliradians [mrad] is multiplied by 0.001. The second variant is a division. Here, the value in milliradians [mrad] is divided by 1,000.

  • Radians [rad] = milliradians [mrad] * 0.001
  • Radians [rad] = milliradians [mrad] ÷ 1,000
