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