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.
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.
