How to Convert Radians to Milliradians

Protractors are often used to measure angle

Convert radians to milliradians with this simple formula:

milliradians = radians × 1,000

Converting a radian angle measurement to a milliradian measurement involves multiplying the angle by the conversion ratio to find the result. One radian is equal to 1,000 milliradians, so to convert simply multiply by 1,000.

For example:
5 rad = (5 × 1,000) = 5,000 mrad

Radians and milliradians are both units used to measure angle. Learn more about angle and find more angle measurement conversion calculators. Radians are an angle measurement and can be abbreviated as rad, for example 1 rad. Milliradians are an angle measurement and can be abbreviated as mrad, for example 1 mrad.

A radian is the measurement of the angle from the start to the end of an arc equal to the radius of the circle. 1 radian is equal to 180/π, or about 57.29578°. There are about 6.28318 radians in a circle. The radian is the standard SI unit of measurement for an angle.

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