About this conversion
Attogray and Hectosievert are units used in the radiation family of measurements. Attogray measures absorbed radiation dose (energy deposited per unit mass), while Hectosievert 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 Attogray = 1e-20 Hectosieverts (equivalently 1 Hectosievert = 1e+20 Attograys), so results stay accurate for nuclear medicine, radiation safety, health physics, and scientific research.
