About this conversion
Femtogray and Attosievert are units used in the radiation family of measurements. Femtogray 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 Femtogray = 1000 Attosieverts (equivalently 1 Attosievert = 0.001 Femtograys), so results stay accurate for nuclear medicine, radiation safety, health physics, and scientific research.
