About the Gray to Rad conversion
The conversion factor from Gray (Gy) to Rad (rad) is 100.00, meaning 1 Gy = 100.00 rad and inversely 1 rad = 0.01 Gy. That makes the Gray the larger of the two units in the radiation (dose) category, where the SI base unit is the gray. Every ratio here is derived from the SI/international definition rather than a rounded approximation, so results are stable across repeated conversions.
