About this conversion
Curie and Femtosievert are units used in the radiation family of measurements. Curie measures radioactive activity (the rate of radioactive decay), while Femtosievert 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 Curie = 3.7e+25 Femtosieverts (equivalently 1 Femtosievert = 2.7027027e-26 Curies), so results stay accurate for nuclear medicine, radiation safety, health physics, and scientific research.
