Convert Sieverts to Microsieverts (Sv to µSv)
1 sievert (Sv) = 1000000 microsieverts (µSv). 1 µSv = 0.000001 Sv. Example: 15 Sv = 15 × 1000000 = 15000000 µSv.

How to Convert Sievert to Microsievert
- 1 Sv = 1000000 µSv
- 1 µSv = 0.000001 Sv
- Example: convert 15 Sv to µSv: 15 Sv = 15 × 1000000 µSv = 15000000 µSv
Formula
µSv = Sv × 1000000
Derivation from SI units:
- 1 Sv = 1 J/kg weighted for radiation type (and tissue for effective dose).
- 1 µSv = 10⁻⁶ Sv.
Both units are defined exactly, so the factor is exact. Sievert definition: sievert; Microsievert definition: microsievert.
Worked examples
- A reading of 0.05 Sv converts to 50000 µSv.
0.05 Sv × 1000000 = 50000 µSv - A value of 0.5 Sv is 500000 µSv.
0.5 Sv × 1000000 = 500000 µSv

Where it's used
Sieverts are used for radiation protection limits, while microsieverts appear in geiger counter and dosimeter readings (µSv/h). Both measure equivalent and effective radiation dose, so the conversion is a fixed factor.

Frequently asked questions
How many microsieverts are in 1 sievert?
1 Sv = 1000000 µSv.
How do I convert sieverts to microsieverts?
Multiply the value in Sv by 1000000. For example, 15 Sv × 1000000 = 15000000 µSv.
Is the Sv to µSv conversion exact?
Yes. Both units are defined exactly, and 1 Sv is exactly 1000000 µSv.
