About this conversion
Hectogray and Rem are units used in the radiation family of measurements. Hectogray measures absorbed radiation dose (energy deposited per unit mass), while Rem 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 Hectogray = 10000 Rems (equivalently 1 Rem = 0.0001 Hectograys), so results stay accurate for nuclear medicine, radiation safety, health physics, and scientific research.
