Frequently asked questions
What is the source unit in this conversion?
The source unit is the radian (rad). The radian is the SI angle unit.
What is the destination unit in this conversion?
The destination unit is the milliradian (mrad). One milliradian is 0.001 radians.
How do I convert radian to milliradian?
Multiply the radian value by 1000. For example, 10 rad × 1000 = 10000 mrad.
Is the radian to milliradian conversion exact?
Yes. The relationship between these units is a fixed mathematical or SI-defined ratio, so the conversion factor is exact rather than a measured approximation.
Where is this conversion commonly used?
It's used whenever a value expressed in radian needs to be compared with, or reported in, milliradian, such as in engineering, scientific, or everyday calculations.
Can I convert milliradian back to radian?
Yes. Multiply the milliradian value by 0.001 to get radian.

About this conversion
This page converts radian (rad) to milliradian (mrad) within the angle converter.
The radian is the SI angle unit. One milliradian is 0.001 radians.
The formula is milliradian = radian × 1000, based on each unit's fixed relationship to the angle converter's base unit.
The conversion is exact, since it relies on a fixed numerical ratio between the two units rather than a measured or approximate value.
