About this conversion
Hectogray and Curie are units used in the radiation family of measurements. Hectogray measures absorbed radiation dose (energy deposited per unit mass), while Curie measures radioactive activity (the rate of radioactive decay). This page provides the direct numeric ratio between the two units. This converter uses the precise relationship 1 Hectogray = 2.7027027e-9 Curies (equivalently 1 Curie = 3.7e+8 Hectograys), so results stay accurate for nuclear medicine, radiation safety, health physics, and scientific research.
