About this conversion
Microsievert and Nanogray are units used in the radiation family of measurements. Microsievert measures equivalent radiation dose (biological risk-weighted dose), while Nanogray 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 Microsievert = 1000 Nanograys (equivalently 1 Nanogray = 0.001 Microsieverts), so results stay accurate for nuclear medicine, radiation safety, health physics, and scientific research.
