About this conversion
Microgray and Millisievert are units used in the radiation family of measurements. Microgray measures absorbed radiation dose (energy deposited per unit mass), while Millisievert 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 Microgray = 0.001 Millisieverts (equivalently 1 Millisievert = 1000 Micrograys), so results stay accurate for nuclear medicine, radiation safety, health physics, and scientific research.
