About this conversion
Rad and Kilogray 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 = 1e-5 Kilograys (equivalently 1 Kilogray = 100000 Rads), so results stay accurate for nuclear medicine, radiation safety, health physics, and scientific research.
