Conversion Formula
mrem = Mrem × 1000000000
About Megarems
The megarem (Mrem) equals 10⁶ rem = 10⁴ Sv. Found in legacy radiation hardness assurance (RHA) documentation for space and military electronics: some total ionising dose (TID) test reports specify doses in Mrem(Si); at Mrem-level equivalent doses all organic structures suffer irreparable radiation damage. 1 Mrem = 10⁴ Sv = 10 kSv.
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.
