Convert curie to microcurie

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.

Microcurie

The microcurie equals 10⁻⁶ curies (37,000 Bq), commonly used in nuclear medicine, biological tracer studies, and calibration of radiation measuring instruments.
