How to convert microsieverts to millirems
mrem = µSv × 0.1Multiply the value in microsieverts by 0.1. To go the other way, multiply by 10 (or divide by 0.1).
A microsievert is smaller than a millirem: it takes 10 microsieverts to make one millirem.

About the units
Microsievert (µSv)
A dental X-ray is around 5 µSv. One microsievert equals 0.000001 sieverts (Sv).
Millirem (mrem)
The millirem (mrem) is a unit of equivalent dose. One millirem equals 0.00001 sieverts (Sv).
Frequently asked questions
How many millirems are in one microsievert?
There are 0.1 millirems in one microsievert, and this value is exact by definition.
How do I convert microsieverts to millirems?
Multiply the number of microsieverts by 0.1. For example, 10 µSv × 0.1 = 1 mrem.
How many microsieverts are in one millirem?
One millirem equals 10 microsieverts. That is the reverse factor, 1 ÷ 0.1.
What is 10 microsieverts in millirems?
10 µSv = 1 mrem.
Is this µSv to mrem 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.
