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