About this conversion
Petasievert and Gray are units used in the radiation family of measurements. Petasievert measures equivalent radiation dose (biological risk-weighted dose), while Gray 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 Petasievert = 1e+15 Grays (equivalently 1 Gray = 1e-15 Petasieverts), so results stay accurate for nuclear medicine, radiation safety, health physics, and scientific research.
