How to Convert Circles to Milliradians

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

Since one circle is equal to 6,283.185307 milliradians, you can use this simple formula to convert:

milliradians = circles × 6,283.185307

The angle in milliradians is equal to the circles multiplied by 6,283.185307.

For example, here's how to convert 5 circles to milliradians using the formula above.

5 cir = (5 × 6,283.185307) = 31,415.926536 mrad

How Many Milliradians Are in a Circle?

There are 6,283.185307 milliradians in a circle, which is why we use this value in the formula above.

1 cir = 6,283.185307 mrad

What is a Circle?

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.

A circle is more commonly used to describe a round, symmetrical shape with no corners or edges than it is to describe plane angle. The shape is described by its radius and circumference.

What 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.

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.
