About this conversion
Sievert and Rad are units used in the radiation family of measurements. Sievert 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 Sievert = 100 Rads (equivalently 1 Rad = 0.01 Sieverts), so results stay accurate for nuclear medicine, radiation safety, health physics, and scientific research.
