Convert Nanosieverts to Millirems
Convert Nanosieverts (nSv) to Millirems (mrem) instantly and accurately.
Conversion Formula
mrem = nSv × 0.0001
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.
About Millirems
The millirem (mrem) equals 10⁻³ rem = 10⁻⁵ Sv. Standard unit in US radiation protection: NRC occupational whole-body limit 5000 mrem/year; US average annual background ~300 mrem; EPA drinking-water dose limit 4 mrem/year; dose rates near US nuclear plant boundaries are reported in mrem/year. 1 mrem = 10⁻⁵ Sv = 10 µSv.
