Convert Femtograys to Milligrays
Convert Femtograys (fGy) to Milligrays (mGy) instantly and accurately.
Conversion Formula
mGy = fGy × 1.000000000e-12
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 Milligrays
The milligray (mGy) equals 10⁻³ Gy and is the standard unit for diagnostic radiology patient doses. CT head scan ~20-60 mGy; abdominal CT ~10-30 mGy; mammography mean glandular dose ~1-3 mGy. IAEA and EU medical exposure directives set diagnostic reference levels in mGy. 1 mGy = 10⁻³ Gy = 0.1 rad.
