Convert Nanosieverts to Millisieverts
Convert Nanosieverts (nSv) to Millisieverts (mSv) instantly and accurately.
Conversion Formula
mSv = nSv × 1.000000000e-6
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 Millisieverts
The millisievert (mSv) equals 10⁻³ Sv and is the primary international radiation protection unit. ICRP 103 occupational limit 20 mSv/year averaged over 5 years; worldwide average background ~2.4 mSv/year; abdominal CT ~10 mSv; EU medical exposure directive and IAEA dose limits are quoted in mSv. 1 mSv = 10⁻³ Sv = 100 mrem.
