About this conversion
Gigasievert and Yoctogray are units used in the radiation family of measurements. Gigasievert measures equivalent radiation dose (biological risk-weighted dose), while Yoctogray 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 Gigasievert = 1e+33 Yoctograys (equivalently 1 Yoctogray = 1e-33 Gigasieverts), so results stay accurate for nuclear medicine, radiation safety, health physics, and scientific research.
