About this conversion
Gigagray and Terasievert are units used in the radiation family of measurements. Gigagray measures absorbed radiation dose (energy deposited per unit mass), while Terasievert 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 Gigagray = 0.001 Terasieverts (equivalently 1 Terasievert = 1000 Gigagrays), so results stay accurate for nuclear medicine, radiation safety, health physics, and scientific research.
