Convert Microsieverts to Sieverts (µSv to Sv)
1 microsievert (µSv) = 0.000001 sieverts (Sv). 1 Sv = 1000000 µSv. Example: 15 µSv = 15 × 0.000001 = 0.000015 Sv.

How to Convert Microsievert to Sievert
- 1 µSv = 0.000001 Sv
- 1 Sv = 1000000 µSv
- Example: convert 15 µSv to Sv: 15 µSv = 15 × 0.000001 Sv = 0.000015 Sv
Formula
Sv = µSv ÷ 1000000
Derivation from SI units:
- 1 µSv = 10⁻⁶ Sv.
- 1 Sv = 1 J/kg weighted for radiation type (and tissue for effective dose).
Both units are defined exactly, so the factor is exact. Microsievert definition: microsievert; Sievert definition: sievert.
Worked examples
- A reading of 5 µSv converts to 0.000005 Sv.
5 µSv × 0.000001 = 0.000005 Sv - A value of 40 µSv is 0.00004 Sv.
40 µSv × 0.000001 = 0.00004 Sv
Microsievert to Sievert conversion table
| Microsieverts (µSv) | Sieverts (Sv) |

| 1 µSv | 0.000001 Sv |
| 5 µSv | 0.000005 Sv |
| 10 µSv | 0.00001 Sv |
| 20 µSv | 0.00002 Sv |
| 40 µSv | 0.00004 Sv |
| 100 µSv | 0.0001 Sv |

| 5000 µSv | 0.005 Sv |
Where it's used
Microsieverts are used for geiger counter and dosimeter readings (µSv/h), while sieverts appear in radiation protection limits. Both measure equivalent and effective radiation dose, so the conversion is a fixed factor.

Frequently asked questions
How many sieverts are in 1 microsievert?
1 µSv = 0.000001 Sv.
How do I convert microsieverts to sieverts?
Multiply the value in µSv by 0.000001, or divide it by 1000000. For example, 15 µSv × 0.000001 = 0.000015 Sv.
Is the µSv to Sv conversion exact?
Yes. Both units are defined exactly, and 1 µSv is exactly 0.000001 Sv.
