About this conversion
Curie and Petagray are units used in the radiation family of measurements. Curie measures radioactive activity (the rate of radioactive decay), while Petagray measures absorbed radiation dose (energy deposited per unit mass). This page provides the direct numeric ratio between the two units. This converter uses the precise relationship 1 Curie = 3.7e-5 Petagrays (equivalently 1 Petagray = 27027.02703 Curies), so results stay accurate for nuclear medicine, radiation safety, health physics, and scientific research.
