About this conversion
Femtosievert and Curie are units used in the radiation family of measurements. Femtosievert measures equivalent radiation dose (biological risk-weighted dose), while Curie measures radioactive activity (the rate of radioactive decay). This page provides the direct numeric ratio between the two units. This converter uses the precise relationship 1 Femtosievert = 2.7027027e-26 Curies (equivalently 1 Curie = 3.7e+25 Femtosieverts), so results stay accurate for nuclear medicine, radiation safety, health physics, and scientific research.
