Femtograys (fGy)
Kilograys (kGy)

Conversion Formula

kGy = fGy × 1.000000000e-18

About Femtograys

The femtogray (fGy) equals 10⁻¹⁵ Gy, used in radiation biology to characterise the dose deposited by a single low-energy Auger electron cascade or a single traversal of a low-LET particle through a cell nucleus. Monte Carlo microdosimetry simulations of targeted radionuclide therapy report subcellular doses at the fGy level. 1 fGy = 10⁻¹⁵ Gy = 10⁻³ pGy.

About Kilograys

The kilogray (kGy) equals 10³ Gy and is the standard unit for radiation processing. Food irradiation: 1-10 kGy for insect disinfestation and sprout inhibition; medical device sterilisation standard dose is 25 kGy (ISO 11137); polymer crosslinking and cable insulation curing use 50-200 kGy. 1 kGy = 10³ Gy = 10⁵ rad.
