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