About this conversion
Gray and Centisievert are units used in the radiation family of measurements. Gray measures absorbed radiation dose (energy deposited per unit mass), while Centisievert 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 Gray = 100 Centisieverts (equivalently 1 Centisievert = 0.01 Grays), so results stay accurate for nuclear medicine, radiation safety, health physics, and scientific research.
