Microsieverts to Rems formula and what each symbol means
rem = µSv × 0.0001
| Symbol | Meaning |
|---|---|
| µSv | Microsievert |
| rem | Rem |
Microsieverts to Rems examples
1 µSv
1 µSv × 0.0001 = 0.0001 rem.
10 µSv
10 µSv × 0.0001 = 0.001 rem.
100 µSv
100 µSv × 0.0001 = 0.01 rem.
Microsieverts compared with Rems
One rem is 10,000 times as large as one µSv, so your number gets smaller when you convert microsieverts to rems and bigger when you convert back. If the answer is not smaller than what you typed, you multiplied instead of dividing.
About microsieverts and rems
Microsievert (µSv): Microsievert, 1×10⁻⁶ Sv. Rem (rem): The rem, exactly 0.01 Sv.
How to calculate Microsieverts to Rems step by step
- Enter the value in µSv (the starting unit).
- Multiply by 0.0001, because 1 µSv = 0.0001 rem.
- The product is the value in rem. To go back, divide by 0.0001 or multiply by 10,000.

Common mistakes when calculating Microsieverts to Rems
- Mixing rem and mrem, which differ by 1,000.
- Dividing when you should multiply: from µSv to rem multiply by 0.0001; from rem to µSv divide by 0.0001.
Microsieverts to Rems FAQ
