radian to milliradian
Convert radian (rad) to milliradian (mrad). Use an editable angle converter, conversion formula, and reference table.
1 rad = 1,000 mrad
Conversion formula
One radian equals 1,000 milliradian. Multiply your value in radian by this factor to get milliradian. For the reverse conversion, divide by the same factor.
Worked example
To convert 5 radian:5 × 1,000 = 5,000 mrad

About these measurements
An angle describes rotation between directions.
The base reference used here is the radian. One radian is 1 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.
Common questions
How do I convert rad to mrad?
Multiply the quantity in rad by 1,000. You can also type the value into the converter above.
Can I reverse the conversion?
Yes. Use the swap button or open the milliradian to radian converter.
