Conversion formula

m° = gon × 900

One gradian equals 900 millidegree. Multiply your value in gradian by this factor to get millidegree. For the reverse conversion, divide by the same factor.

Worked example

To convert 5 gradian:
5 × 900 = 4,500 m°

About these measurements

An angle describes rotation between directions.

The base reference used here is the radian. One gradian is 0.01570796327 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.

Common questions
