Convert Femtosieverts to Megarems
Convert Femtosieverts (fSv) to Megarems (Mrem) instantly and accurately.
Conversion Formula
Mrem = fSv × 1.000000000e-19
About Femtosieverts
The femtosievert (fSv) equals 10⁻¹⁵ Sv. Used in computational nanodosimetry and Monte Carlo particle-transport simulations to characterise the equivalent dose from a single ion traversal through a DNA segment or cell organelle. Ultra-sensitive detector calibration in deep underground laboratories approaches the fSv level. 1 fSv = 10⁻¹⁵ Sv = 10⁻³ pSv.
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.
