Radians to Milliradians Conversion
Radians and milliradians both measure angles; milliradians are one-thousandth of a radian. Conversion requires multiplying or dividing by 1000, a simple scale factor. This is widely used in ballistics and engineering for small angle approximations.

Radians → Milliradians
Converting Radians (rad) to Milliradians (mrad) is a common angle conversion. 1 rad equals 1,000 mrad. For example, 100 rad is equal to 100,000 mrad.
Quick Mental Math: Radians to Milliradians
To convert radians to milliradians, multiply by 1000; for milliradians to radians, divide by 1000.
Why is converting Radians to Milliradians tricky?
Mistaking milliradians as a different angular system instead of a submultiple of radians causes confusion.
Quick Reference Values
1 rad = 1,000 mrad. 5 rad = 5,000 mrad. 10 rad = 10,000 mrad. 25 rad = 25,000 mrad. 50 rad = 50,000 mrad. 100 rad = 100,000 mrad.
What is Radians?
Radians (rad) is a unit of angle. A radian is the SI unit of plane angle defined as the angle subtended at the center of a circle by an arc equal in length to the radius. One radian equals approximately 57.2958 degrees or exactly 1 rad = radius/arc length ratio. It is a dimensionless unit used extensively in mathematics, physics, and engineering [bipm-si-brochure]. The radian concept was formalized in the 19th century, with mathematicians like Roger Cotes contributing to its development. The radian was adopted as the standard angular unit in the SI system to provide a natural measure of angles based on circle geometry [bipm-si-brochure]. Radians are the standard unit of angular measurement in science, engineering, and technology worldwide. They are used in trigonometry, rotational dynamics, and signal processing, with formal adoption by the BIPM and ISO 80000 standards [bipm-si-brochure, iso-80000].
What is Milliradians?
Milliradians (mrad) is a unit of angle. The milliradian (mrad) is an angular measurement unit equal to one-thousandth of a radian. Since 1 radian equals approximately 57.2958 degrees, 1 mrad equals 0.0573 degrees. It is primarily used in ballistics, optics, and surveying for angular precision [bipm-si-brochure]. The radian was formally defined in the early 20th century as a standard SI unit of angle. The milliradian emerged as a practical subdivision for fine angular measurements, adopted by military and scientific communities for targeting and measurement accuracy [nist-si-guide]. Milliradians are standard in NATO countries' military aiming devices, European surveying, and optical instrumentation globally. The unit is recognized by BIPM as a derived SI unit for plane angle [bipm-si-brochure].
Common Misspellings
People often search for this conversion using these alternate spellings: radianes, radias, radans, radiens, milli radian, millirad, miliradian, mradn, milirads. All of these refer to the Radians to Milliradians conversion.
FAQ
Is there any offset in converting radians to milliradians?
No. The conversion is a direct scale factor with 1 radian = 1000 milliradians.
