How to convert millirem to microsieverts
To convert millirem to microsieverts, multiply the number of millirem by 10.
Formula
µSv = mrem × 10
Examples
- 5 mrem = 5 × 10 = 50 µSv
- 25 mrem = 25 × 10 = 250 µSv
- 100 mrem = 100 × 10 = 1000 µSv

Frequently asked questions
- How many microsieverts are in one millirem?
- One millirem is exactly 10 microsieverts.
- How do I convert microsieverts to millirem?
- To convert microsieverts to millirem, multiply the number of microsieverts by 0.1. The formula is mrem = µSv × 0.1.
- Is this conversion exact?
- Yes. Both units have exact definitions and the factor 10 is exact. Displayed results are only rounded when they have many decimal places.
- Which is larger, a millirem or a microsievert?
- A millirem is 10 times larger than a microsievert. In other words, a microsievert is exactly 1/10 of a millirem.
