About this conversion
Rad and Hectogray are units used in the radiation family of measurements. Both units measure absorbed radiation dose (energy deposited per unit mass). This converter uses the precise relationship 1 Rad = 0.0001 Hectograys (equivalently 1 Hectogray = 10000 Rads), so results stay accurate for nuclear medicine, radiation safety, health physics, and scientific research.
