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