What does femtogray measure?

Femtogray measures extremely small absorbed radiation doses typically at microscopic or single-event scales, equal to 10^-15 joules of radiation energy per kilogram.

When should I use nanogray units?

Nanogray units are used for very small radiation doses common in environmental monitoring, public exposure assessments, and low-level radiological surveys.

Is there any precision loss when converting between these units?

Yes, because femtograys and nanograys represent vastly different scales (10^-15 vs 10^-9 gray), some precision loss can occur during conversion.
