Convert curie to picocurie

Curie

The curie is the historical unit of radioactivity, originally defined as the decay rate of one gram of radium-226. One curie equals 3.7×10¹⁰ becquerels.

Picocurie

The picocurie equals 10⁻¹² curies and is commonly used to measure radon activity in homes and the radioactivity of environmental water and air samples.
