What does joule/centigram measure?

Joule per centigram quantifies absorbed radiation dose as energy deposited in joules per 0.01 gram of material, representing an energy per mass unit.

When is petagray typically used?

Petagray is used primarily for extremely large, often theoretical radiation doses, such as those in astrophysics or high-energy physics modeling.

How do I convert from J/cg to PGy?

Multiply the value in joule/centigram by 1e-10 to obtain the equivalent dose in petagray.
