Use this page to convert nanogray values into gray, with background details, formulas, a worked example, and a quick conversion table.

1 nGy = 0.000000001 Gy

1 Gy = 1,000,000,000 nGy

Example: 1 nGy = 0.000000001 Gy

One nanogray is one billionth of a gray (1.0E-9 grays).

History: SI prefix nano- applied to the gray.

Current use: Used for precise environmental radiation monitoring.

Also written as nGy.

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.
