What is a petagray (PGy)?

A petagray is an SI-derived unit of absorbed radiation dose equal to 10^15 grays, representing an extremely large amount of energy absorbed per kilogram of matter.

Why convert from petagray to hectogray?

Converting petagray to hectogray expresses very large absorbed doses in a smaller, more manageable unit to assist in industrial and dosimetry reporting.

Where is the petagray unit typically used?

Petagray is mainly used in theoretical studies, astrophysics, extreme radiation event modeling, and advanced high-energy physics research.

Are these large unit conversions common in everyday radiation measurements?

No, practical radiation doses found in usual scenarios are much smaller, so petagray to hectogray conversions are mostly limited to specialized fields.
