What does 1 centigray represent in terms of gray?

1 centigray (cGy) is equal to one hundredth of a gray (Gy), which is the unit measuring absorbed radiation energy per kilogram.

When should I use femtograys for radiation dose measurement?

Femtogray (fGy) measurements are used for very small radiation doses in fields like microdosimetry and radiobiology, focusing on microscopic or single-event energy depositions.

Can I use this converter for everyday clinical dose reports?

No, this converter is mainly designed for highly sensitive research and detector calibration rather than routine clinical dose reporting.
