About this conversion
Yottagray and Attosievert are units used in the radiation family of measurements. Yottagray measures absorbed radiation dose (energy deposited per unit mass), while Attosievert 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 Yottagray = 1e+42 Attosieverts (equivalently 1 Attosievert = 1e-42 Yottagrays), so results stay accurate for nuclear medicine, radiation safety, health physics, and scientific research.
