What is a teragray (TGy)?

A teragray is an SI-derived unit of absorbed radiation dose equivalent to 10^12 grays, used for very large energy deposition values.

How is petagray (PGy) different from teragray (TGy)?

Petagray represents a larger absorbed dose unit equal to 10^15 grays, which is 1000 times greater than one teragray.

Why convert between teragray and petagray?

Conversion helps express extremely large absorbed doses in a simpler numeric form suitable for theoretical or high-energy radiation scenarios.
