Convert curie to becquerel

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.

Becquerel

The becquerel is the SI unit of radioactivity, defined as one nuclear decay per second. Named after Henri Becquerel, it replaced the curie as the standard unit of radioactive decay rate.
