What this calculator does
Converts a measurement given in millisieverts into microsieverts using the defined conversion factor.
What your result means
The same quantity expressed in µSv instead of mSv. Nothing about the measurement itself changes.
Formula and working
µSv = mSv × 1,000
- 1
Start with your value
10 mSv
- 2
Convert to sievert
10 × 0.001 = 0.01 Sv
- 3
Convert into microsieverts
0.01 ÷ 0.000001 = 10,000 µSv
- 4
Result
10 mSv = 10,000 µSv
Frequently asked questions
Symbols and assumptions
- mSv
- Input unit — millisievert
- µSv
- Output unit — microsievert
- Sv
- Base unit used internally for radiation dose
- • Both units measure radiation dose, so the physical quantity is unchanged by the conversion.
- • The relationship is exactly linear: 1 mSv = 1,000 µSv.
- • Values are converted through the SI base unit for this quantity rather than pair by pair.
Sources and review
Reviewed 2026-09-22 · Next review 2027-09-22
- • A unit conversion changes how a number is expressed, not how it was measured — the answer can never be more accurate than the value entered.
- • Displayed figures are rounded for readability; the full stored precision of the µSv value is used in every onward calculation.
