What does 1 W/kg represent in radiation dosimetry?

1 W/kg represents the rate of energy absorbed per unit mass and is equivalent numerically to 1 gray per second, indicating the dose rate of ionizing radiation.

When is it appropriate to use petagray per second units?

Petagray per second units are suited for describing extremely high dose rates found in nuclear detonations, reactor accidents, or astrophysical phenomena.

How do I convert watt per kilogram to petagray per second?

Multiply the value in watt per kilogram by 1e-15 to get the equivalent dose rate in petagray per second.

Limitations

Petagray per second unit applies only to extraordinarily high dose rates, not everyday contexts
1 W/kg corresponds to a tiny fraction (1e-15) of a PGy/s, so numerical precision is critical
Converting very large or very small numbers may require advanced computational accuracy
This tool does not provide clinical, safety, or regulatory dose limit guidance
