Conversion Formula

fSv = kSv × 1.000000000e+18

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.

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.
