About this conversion

Megagray and Exasievert are units used in the radiation family of measurements. Megagray measures absorbed radiation dose (energy deposited per unit mass), while Exasievert 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 Megagray = 1e-12 Exasieverts (equivalently 1 Exasievert = 1e+12 Megagrays), so results stay accurate for nuclear medicine, radiation safety, health physics, and scientific research.
