What is a femtogray (fGy)?

A femtogray is a unit of radiation absorbed dose equal to 10⁻¹⁵ gray, representing extremely small energy depositions from ionizing radiation at microscopic scales.

What does teragray (TGy) measure?

The teragray is an SI-derived unit equal to 10¹² gray, used to quantify very large absorbed radiation doses in high-energy or extreme environments.

Why convert from femtogray to teragray?

This conversion helps relate tiny absorbed radiation doses to vastly larger theoretical or high-energy dose scales, enabling comparison across very different magnitudes.
