Milliradians to Radians (mrad to rad) Converter

How to convert milliradians to radians

Formularad = mrad × 0.001

Multiply the value in milliradians by 0.001. To go the other way, multiply by 1,000 (or divide by 0.001).

A milliradian is smaller than a radian: it takes 1,000 milliradians to make one radian.

About the units

Milliradian (mrad)

The milliradian (mrad) is a unit of angle in the International System of Units (SI). One milliradian equals 0.001 radians (rad).

Radian (rad)

The angle subtended by an arc equal in length to the radius; 2π rad make a full turn, so 1 rad ≈ 57.2958°.

Frequently asked questions

How many radians are in one milliradian?

There are 0.001 radians in one milliradian, and this value is exact by definition.

How do I convert milliradians to radians?

Multiply the number of milliradians by 0.001. For example, 10 mrad × 0.001 = 0.01 rad.

How many milliradians are in one radian?

One radian equals 1,000 milliradians. That is the reverse factor, 1 ÷ 0.001.

What is 10 milliradians in radians?

10 mrad = 0.01 rad.

Is this mrad to rad converter accurate?

Yes. Both units are defined exactly in terms of SI units, so the conversion factor is exact; results are shown to 12 significant figures by default and you can change precision in the converter. Calculations run in your browser using the same tested engine that generated this page.
