Megarems (Mrem)
Megasieverts (MSv)

Conversion Formula

MSv = Mrem × 0.01

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 Megasieverts

The megasievert (MSv) equals 10⁶ Sv. Entirely theoretical for biological contexts - severe radiation damage occurs well below 1 MSv. Appears in materials science modelling of extreme radiation environments, theoretical nuclear detonation effects at point of burst, and advanced reactor pressure vessel damage accumulation calculations. 1 MSv = 10⁶ Sv = 10⁸ rem.
