1 fGy = 1e-15 Gy

1 Gy = 1,000,000,000,000,000 fGy

Example: 1 fGy = 1e-15 Gy

One femtogray is one quadrillionth of a gray (1.0E-15 grays).

History: SI prefix femto- applied to the gray.

Current use: Purely theoretical or specialized physics.

Also written as fGy.

Defined as the absorption of one joule of radiation energy per kilogram of matter.

History: Named after Louis Harold Gray, a pioneer in the field of radiobiology. Adopted by the CGPM in 1975.

Current use: The primary international unit used in radiotherapy, radiation protection, and radiobiology.

Also written as Gy, grays.
