A femtogray is an SI unit of absorbed radiation dose equal to 10^-15 gray, used for measuring extremely small energy depositions in microscopic or single-event radiation studies.

What scenarios use gigagray measurements?

Gigagrays are applied to quantify extraordinarily high radiation doses such as those in astrophysical events, materials testing under extreme conditions, and nuclear accelerator safety analyses.

Why is converting between fGy and GGy challenging?

Because femtograys and gigagrays differ by a factor of 10^24, conversions involve very small or large numbers making exact precision and representation difficult.
