About this conversion
Rem and Attogray are units used in the radiation family of measurements. Rem measures equivalent radiation dose (biological risk-weighted dose), while Attogray 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 Rem = 1e+16 Attograys (equivalently 1 Attogray = 1e-16 Rems), so results stay accurate for nuclear medicine, radiation safety, health physics, and scientific research.
