How to convert sieverts to microsieverts
µSv = Sv × 1,000,000Multiply the value in sieverts by 1,000,000. To go the other way, multiply by 0.000001 (or divide by 1,000,000).
A sievert is larger than a microsievert: one sievert contains 1,000,000 microsieverts.

About the units
Sievert (Sv)
The sievert (Sv) is a unit of equivalent dose in the International System of Units (SI).
Microsievert (µSv)
A dental X-ray is around 5 µSv. One microsievert equals 0.000001 sieverts (Sv).
Frequently asked questions
How many microsieverts are in one sievert?
There are 1,000,000 microsieverts in one sievert, and this value is exact by definition.
How do I convert sieverts to microsieverts?
Multiply the number of sieverts by 1,000,000. For example, 10 Sv × 1,000,000 = 10,000,000 µSv.
How many sieverts are in one microsievert?
One microsievert equals 0.000001 sieverts. That is the reverse factor, 1 ÷ 1,000,000.
What is 10 sieverts in microsieverts?
10 Sv = 10,000,000 µSv.
Is this Sv to µSv converter accurate?
Yes. Both units are defined exactly in terms of SI units, so the conversion factor is exact; results are shown to 12 significant figures by default and you can change precision in the converter. Calculations run in your browser using the same tested engine that generated this page.
