0.1mR

Nothing on our list is smaller: a chest X-ray is 150× more.

What it means

How much exposure is that?

Information only. Medical figures are typical entrance exposures and vary widely with equipment and patient. For dose to people, use gray and sievert.

The math

How to convert µR to mR

To convert microroentgen to milliroentgen, multiply by 0.001.

Example: 100 µR × 0.001 = 0.1 mR.

In the other direction, 1 mR = 1,000 µR.
