A milliradian is a unit used to measure angle.
The milliradian is a multiple of the radian, which is the SI derived unit for angle. In the metric system, "milli" is the prefix for thousandths, or 10-3. A milliradian is sometimes also referred to as a mil. Milliradians can be abbreviated as mrad; for example, 1 milliradian can be written as 1 mrad.
How Much Is a Milliradian?
A milliradian is equal to 1/1,000 of a radian. One milliradian is equal to 0.0573 degrees and there are 6,283 milliradians in a full revolution/circle. The milliradian is also a commonly used unit in mathematics.
How to Convert Milliradians
To convert milliradians to another unit of angle, you need to multiply the value by a conversion factor. A conversion factor is a numerical value used to change the units of a measurement without changing the value.[1]
You can find the conversion factors for milliradians in the conversion table below.
Then, multiply the angle measurement by the conversion factor to find the equivalent value in the desired unit of measurement.
milliradians × conversion factor = result
You can also use a calculator, such as one of the converters below, for the conversion.
