This converter allows you to convert arcminutes [′] to milliradians [mrad] or milliradians [mrad] to arcminutes [′]. 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 arcminute [′] ≈ 0.2909 milliradians [mrad]1 milliradian [mrad] ≈ 3.4377 arcminutes [′]

Convert arcminutes to milliradians

There are two simple ways to convert arcminutes [′] to milliradians [mrad]. In the first calculation method, the value in arcminutes [′] is divided by the rounded conversion factor of 3.4377. The second method multiplies the value in arcminutes [′] by the rounded conversion factor of 0.2909.

  • Milliradians [mrad] ≈ arcminutes [′] ÷ 3.4377
  • Milliradians [mrad] ≈ arcminutes [′] * 0.2909

However, rounded conversion values are only suitable for rough conversions, as rounding errors can occur in the calculation result. The most accurate conversion of arcminutes [′] to milliradians [mrad] can be achieved using the following calculation method.

  • Milliradians [mrad] = (arcminutes [′] * π ÷ 108) * 10

Convert milliradians to arcminutes

Converting milliradians [mrad] to arcminutes [′] is easy and can be done in two ways. The first method involves multiplication, in which the value in milliradians [mrad] is multiplied by the rounded conversion factor of 3.4377. The second variant is a division. Here, the value in milliradians [mrad] is divided by the rounded conversion factor of 0.2909.

  • Arcminutes [′] ≈ milliradians [mrad] * 3.4377
  • Arcminutes [′] ≈ milliradians [mrad] ÷ 0.2909

However, rounded conversion values do not allow for exact calculations because rounding errors can occur in the calculation result. The most accurate conversion of milliradians [mrad] to arcminutes [′] can be achieved using the following calculation method.

  • Arcminutes [′] = (milliradians [mrad] * 108 ÷ π) ÷ 10
