Results in Circles: ## How to Convert Milliradians to Circles

To convert a milliradian measurement to a circle measurement, multiply the angle by the conversion ratio.

Since one milliradian is equal to 0.000159 circles, you can use this simple formula to convert:

The angle in circles is equal to the milliradians multiplied by 0.000159.

For example, here's how to convert 5,000 milliradians to circles using the formula above.
5,000 mrad = (5,000 × 0.000159) = 0.795775 cir

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.

## Circles

A circle is the equivalent of 1 revolution around a circle, or 360°.

A circle is sometimes also referred to as a revolution. Circles can be abbreviated as cir; for example, 1 circle can be written as 1 cir.
