Convert Rems to Nanosieverts
Convert Rems (rem) to Nanosieverts (nSv) instantly and accurately.
Conversion Formula
nSv = rem × 10000000
About Rems
The rem (roentgen equivalent man) equals exactly 0.01 Sv = 1 cSv. The pre-SI unit of equivalent dose, still dominant in US regulation: NRC occupational whole-body limit 5 rem/year; 10 CFR Part 20 exposure limits cited in rem; US military personnel dose records maintained in rem. 1 rem = 0.01 Sv = 1 cSv.
About Nanosieverts
The nanosievert (nSv) equals 10⁻⁹ Sv. Ambient environmental gamma dose rates at sea level are ~30-50 nSv/h; portable radiation survey meters and environmental monitoring networks report ambient dose equivalent rates in nSv/h; airborne gamma spectrometry surveys record deposition rates in nSv/h. 1 nSv = 10⁻⁹ Sv = 10⁻³ µSv.
