About this conversion
Hectosievert and Megagray are units used in the radiation family of measurements. Hectosievert measures equivalent radiation dose (biological risk-weighted dose), while Megagray 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 Hectosievert = 0.0001 Megagrays (equivalently 1 Megagray = 10000 Hectosieverts), so results stay accurate for nuclear medicine, radiation safety, health physics, and scientific research.
