A gigagray (GGy) is an SI-derived unit of absorbed radiation dose equal to 10^9 gray, used for extraordinarily large doses in scientific and engineering applications.

What does attogray represent?

An attogray (aGy) is 10^-18 of a gray and is used to describe extremely small amounts of absorbed radiation in sensitive measurements.

Why convert from gigagray to attogray?

The conversion helps bridge contexts where radiation doses differ dramatically, enabling consistent reporting and comparisons across scientific and engineering fields.

Can this converter be used for regular radiation dose measurements?

No, gigagray and attogray units are specialized for extremely large or extremely small doses respectively and are not suitable for typical dose ranges.
