Microsieverts to Millirems formula and what each symbol means
mrem = µSv × 0.1
| Symbol | Meaning |
|---|---|
| µSv | Microsievert |
| mrem | Millirem |
Microsieverts to Millirems examples
1 µSv
1 µSv × 0.1 = 0.1 mrem.
10 µSv
10 µSv × 0.1 = 1 mrem.
100 µSv
100 µSv × 0.1 = 10 mrem.
Microsieverts compared with Millirems
One mrem is 10 times as large as one µSv, so your number gets smaller when you convert microsieverts to millirems and bigger when you convert back. If the answer is not smaller than what you typed, you multiplied instead of dividing.
About microsieverts and millirems
Microsievert (µSv): Microsievert, 1×10⁻⁶ Sv. Millirem (mrem): Millirem, exactly 1×10⁻⁵ Sv.
How to calculate Microsieverts to Millirems step by step
- Enter the value in µSv (the starting unit).
- Multiply by 0.1, because 1 µSv = 0.1 mrem.
- The product is the value in mrem. To go back, divide by 0.1 or multiply by 10.

Common mistakes when calculating Microsieverts to Millirems
- Confusing the sievert (biological effect) with the gray (energy absorbed).
- Dividing when you should multiply: from µSv to mrem multiply by 0.1; from mrem to µSv divide by 0.1.
Microsieverts to Millirems FAQ
