About these units
Curies
The curie is an older unit equal to 3.7 × 10¹⁰ becquerels, originally the activity of one gram of radium.
Becquerels
The becquerel is the SI unit of radioactivity, equal to one nuclear decay per second. It's a very small unit, so multiples are common.
Conversion formula
To convert Curie to Becquerel, multiply the value by 37,000,000,000 (3.7 × 10¹⁰).
