# Minutes Of Arc to Milliradians Conversion

Enter the angle in minutes of arc below to get the value converted to milliradians. ## How to Convert Minutes Of Arc to Milliradians To convert a minute of arc measurement to a milliradian measurement, multiply the angle by the conversion ratio. One minute of arc is equal to 0.290888 milliradians, so use this simple formula to convert:

milliradians = minutes of arc × 0.290888

The angle in milliradians is equal to the minutes of arc multiplied by 0.290888.

For example, here's how to convert 5 minutes of arc to milliradians using the formula above.
5' = (5 × 0.290888) = 1.454441 mrad

## Minutes Of Arc

The minute of arc is a unit of angle equal to 1/60th of one degree, or 1/21,600 of a circle. The minute of arc is also equal to π/10,800 radians.

A minute of arc is sometimes also referred to as an arc minute, arcminute, or minute arc. Minutes of arc can be abbreviated as arcmin, and are also sometimes abbreviated as MOA or amin. For example, 1 minute of arc can be written as 1 arcmin, 1 MOA, or 1 amin.

The minute of arc is most commonly represented using the prime (′), although the single-quote is commonly used. For instance, 1 minute of is most commonly expressed as 1′.

A milliradian is equal to 1/1,000 of a radian. One degree is equal to 0.0573 milliradians and there are 6,283 milliradians in a full revolution/circle. The milliradian is also a commonly used unit in mathematics.

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 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.
