Conversion formula

m° = ° × 1,000

One degree equals 1,000 millidegree. Multiply your value in degree by this factor to get millidegree. For the reverse conversion, divide by the same factor.

Worked example

To convert 5 degree:
5 × 1,000 = 5,000 m°

About these measurements

An angle describes rotation between directions.

The base reference used here is the radian. One degree is 0.01745329252 base units; one millidegree is 0.00001745329252 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.
