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