About this conversion
Yoctosievert and Quectogray are units used in the radiation family of measurements. Yoctosievert measures equivalent radiation dose (biological risk-weighted dose), while Quectogray 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 Yoctosievert = 1000000 Quectograys (equivalently 1 Quectogray = 1e-6 Yoctosieverts), so results stay accurate for nuclear medicine, radiation safety, health physics, and scientific research.
