About this conversion
Megasievert and Exagray are units used in the radiation family of measurements. Megasievert measures equivalent radiation dose (biological risk-weighted dose), while Exagray 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 = 1e-12 Exagrays (equivalently 1 Exagray = 1e+12 Megasieverts), so results stay accurate for nuclear medicine, radiation safety, health physics, and scientific research.
