What is an exagray (EGy)?

The exagray is an SI-derived multiple of the gray equal to 10^18 grays, used to express extremely large absorbed radiation doses primarily in scientific or theoretical contexts.

How is joule per kilogram (J/kg) related to the gray (Gy)?

Joule per kilogram is the SI unit of absorbed dose equivalent to gray, where 1 Gy equals 1 J/kg, used to measure energy deposited by ionizing radiation per unit mass.

Why convert exagray to joule per kilogram?

Converting exagray to joule per kilogram expresses exceptionally large absorbed doses in a more common SI unit, enabling comparison with typical dose measurements in medical, environmental, or experimental settings.
