Convert Microsieverts to Rem (µSv to rem)
1 microsievert (µSv) = 0.0001 rem. 1 rem = 10000 µSv. Example: 15 µSv = 15 × 0.0001 = 0.0015 rem.

How to Convert Microsievert to Rem
- 1 µSv = 0.0001 rem
- 1 rem = 10000 µSv
- Example: convert 15 µSv to rem: 15 µSv = 15 × 0.0001 rem = 0.0015 rem
Formula
rem = µSv ÷ 10000
Derivation from SI units:
- 1 µSv = 10⁻⁶ Sv.
- 1 rem = 0.01 Sv.
- 1 µSv = 0.000001 Sv ÷ 0.01 Sv per rem = 0.0001 rem
Both units are defined exactly, so the factor is exact. Microsievert definition: microsievert; Rem definition: rem.
Worked examples
- A reading of 5 µSv converts to 0.0005 rem.
5 µSv × 0.0001 = 0.0005 rem - A value of 40 µSv is 0.004 rem.
40 µSv × 0.0001 = 0.004 rem

Where it's used
Microsieverts are used for geiger counter and dosimeter readings (µSv/h), while rem appear in US NRC dose limits (5 rem/yr occupational). Both measure equivalent and effective radiation dose, so the conversion is a fixed factor.
Microsievert to other equivalent dose units

Frequently asked questions
How many rem are in 1 microsievert?
1 µSv = 0.0001 rem.
How do I convert microsieverts to rem?
Multiply the value in µSv by 0.0001, or divide it by 10000. For example, 15 µSv × 0.0001 = 0.0015 rem.
Is the µSv to rem conversion exact?
Yes. Both units are defined exactly, and 1 µSv is exactly 0.0001 rem.
