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