Conversion formula

mrad = m° × 0.01745329252

One millidegree equals 0.01745329252 milliradian. Multiply your value in millidegree by this factor to get milliradian. For the reverse conversion, divide by the same factor.

Worked example

To convert 5 millidegree:
5 × 0.01745329252 = 0.0872664626 mrad

About these measurements

An angle describes rotation between directions.

The base reference used here is the radian. One millidegree is 0.00001745329252 base units; one milliradian is 0.001 base units.

Important distinctions

A full turn is 360 degrees or 2π radians. Signed angles are permitted.

Precision

The converter uses stored conversion factors and floating-point arithmetic. Results display up to ten significant digits, switching to scientific notation for very small or large values. Keep the precision of your original measurement when reporting results.
