What does one petagray represent in terms of grays?

One petagray equals 10^15 grays, indicating a tremendously large absorbed radiation dose.

Why would someone convert from petagray to joule per milligram?

This conversion helps express extremely large absorbed doses in terms of energy deposited per milligram, which is useful for small sample or laboratory-scale measurements.

Is joule per milligram commonly used for bulk materials?

No, joule per milligram is mainly practical for small mass samples and may not offer meaningful information when applied to bulk materials without context.
