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