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 Kilosieverts

The kilosievert (kSv) equals 10³ Sv. Doses above ~10 Sv are rapidly lethal; the kSv scale is encountered only in extreme irradiator calibration measurements, high-energy accelerator beam-loss scenarios, and nuclear detonation effects calculations at the closest survival radii. 1 kSv = 10³ Sv = 10⁵ rem.
