How to convert picocuries to curies
Multiply the number of picocuries by 0.000000000001 to get curies.
The exact factor is 0.000000000001 — as a fraction, 1/1000000000000.
Picocurie: Radon in air is reported in pCi/L in the US, Bq/m³ elsewhere.
Curie: Exactly 3.7 × 10¹⁰ Bq — originally the activity of one gram of radium-226.
