About this conversion
Kilosievert and Gray are units used in the radiation family of measurements. Kilosievert measures equivalent radiation dose (biological risk-weighted dose), while Gray 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 Kilosievert = 1000 Grays (equivalently 1 Gray = 0.001 Kilosieverts), so results stay accurate for nuclear medicine, radiation safety, health physics, and scientific research.
