Convert Nanosieverts to Rem (nSv to rem)
1 nanosievert (nSv) = 1 × 10⁻⁷ rem. 1 rem = 10000000 nSv. Example: 15 nSv = 15 × 1 × 10⁻⁷ = 0.0000015 rem.

How to Convert Nanosievert to Rem
- 1 nSv = 1 × 10⁻⁷ rem
- 1 rem = 10000000 nSv
- Example: convert 15 nSv to rem: 15 nSv = 15 × 1 × 10⁻⁷ rem = 0.0000015 rem
Formula
rem = nSv ÷ 10000000
Derivation from SI units:
- 1 nSv = 10⁻⁹ Sv.
- 1 rem = 0.01 Sv.
- 1 nSv = 1 × 10⁻⁹ Sv ÷ 0.01 Sv per rem = 1 × 10⁻⁷ rem
Both units are defined exactly, so the factor is exact. Nanosievert definition: nanosievert; Rem definition: rem.
Worked examples
- A reading of 150 nSv converts to 0.000015 rem.
150 nSv × 1 × 10⁻⁷ = 0.000015 rem - A value of 500 nSv is 0.00005 rem.
500 nSv × 1 × 10⁻⁷ = 0.00005 rem

Where it's used
Nanosieverts are used for environmental radiation monitoring networks, while rem appear in US NRC dose limits (5 rem/yr occupational). Both measure equivalent and effective radiation dose, so the conversion is a fixed factor.

Frequently asked questions
How many rem are in 1 nanosievert?
1 nSv = 1 × 10⁻⁷ rem.
How do I convert nanosieverts to rem?
Multiply the value in nSv by 1 × 10⁻⁷, or divide it by 10000000. For example, 15 nSv × 1 × 10⁻⁷ = 0.0000015 rem.
Is the nSv to rem conversion exact?
Yes. Both units are defined exactly, and 1 nSv is exactly 1 × 10⁻⁷ rem.
