About this conversion
Kilogray and Sievert are units used in the radiation family of measurements. Kilogray 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 Kilogray = 1000 Sieverts (equivalently 1 Sievert = 0.001 Kilograys), so results stay accurate for nuclear medicine, radiation safety, health physics, and scientific research.
