Convert Femtosieverts to Millisieverts
Convert Femtosieverts (fSv) to Millisieverts (mSv) instantly and accurately.
Conversion Formula
mSv = fSv × 1.000000000e-12
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 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.
