How to use it
- Type the value in the milliradians box.
- Read the result in degrees as you type, and pick the precision you need.
- Swap the direction to convert back, or copy the result.
How it is calculated
° = mrad × 0.05729577951
Multiply the value in milliradians by 0.05729577951 to get degrees.
Example
To convert 25 mrad to degrees: 25 × 0.05729577951 = 1.43239 °.

About the units
- Milliradian
- A milliradian is one thousandth of a radian, about 0.0573 degree, used on rifle scopes where it is called MIL or MRAD.
- Degree
- A degree is 1/360 of a full turn, exactly π/180 radians, and is the everyday unit in geometry, navigation and maps.
Limits and caveats
- Results are rounded for display and computed with the browser's floating point precision (about 15 significant digits).
- Both unit factors are exact by their official definitions.
Questions about this tool
How many degrees are in one milliradian?
1 mrad = 0.0572958 ° exactly.
How do I convert milliradians to degrees?
Use ° = mrad × 0.05729577951. For example, 25 mrad = 1.43239 °.
How many milliradians are in one degree?
1 ° = 17.4533 mrad.
Why does my calculator give a strange answer for sine?
It is probably set to radians (RAD) while you are entering degrees. The sine of 30 degrees is 0.5, but the sine of 30 radians is about -0.988, so switch to DEG first.
What is the difference between MOA and MIL on a rifle scope?
MOA is an arcminute, 1/60 of a degree, while a MIL is a milliradian, about 3.438 MOA. At 100 meters a 0.1 MIL click moves impact 1 cm, and 1 MOA moves it about 2.9 cm.
