About this conversion
Centigray and Sievert are units used in the radiation family of measurements. Centigray measures absorbed radiation dose (energy deposited per unit mass), while Sievert measures equivalent radiation dose (biological risk-weighted dose). This page provides the direct numeric ratio between the two units. This converter uses the precise relationship 1 Centigray = 0.01 Sieverts (equivalently 1 Sievert = 100 Centigrays), so results stay accurate for nuclear medicine, radiation safety, health physics, and scientific research.
