1 PGy = 1,000,000,000,000,000 Gy

1 Gy = 1e-15 PGy

Example: 1 PGy = 1,000,000,000,000,000 Gy

One petagray is 1.0E+15 grays.

History: SI prefix peta- applied to the gray.

Current use: Purely theoretical.

Also written as PGy.

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.
