millidegree to deciradian
Convert millidegree (m°) to deciradian (drad). Use an editable angle converter, conversion formula, and reference table.
1 m° = 0.0001745329252 drad
Conversion formula
One millidegree equals 0.0001745329252 deciradian. Multiply your value in millidegree by this factor to get deciradian. For the reverse conversion, divide by the same factor.
Worked example
To convert 5 millidegree:5 × 0.0001745329252 = 0.000872664626 drad

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 deciradian is 0.1 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
