Milliroentgen to microcoulombs per kilogram
Type a value in mR to get it in µC/kg instantly.
25.8µC/kg
That's 1.14× as much exposure as a year of natural background, while a dental X-ray is 2.5× more.
Convert the other way: µC/kg to mR
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 mR to µC/kg
To convert milliroentgen to microcoulombs per kilogram, multiply by 0.258.
Example: 100 mR × 0.258 = 25.8 µC/kg.
In the other direction, 1 µC/kg = 3.87597 mR.
