How to Convert Becquerels to Picocuries
The becquerel and picocurie are both units of radioactivity. 1 becquerel equals 27.027027027 picocuries. This means to convert becquerels to picocuries, you multiply by 27.027027027.
Formula
Step-by-Step Example
Convert 5 Bq to picocuries:
We need to convert becquerels to picocuries
Since 1 Bq = 27.027027027 pCi, multiply by 27.027027027
5 × 27.027027027 = 135.13513514
5 Bq = 135.13513514 pCi

About These Units
Becquerel (Bq)
The becquerel (Bq) is the SI unit of radioactivity, measuring decay rate: one becquerel = one nuclear decay per second. Named after Henri Becquerel who discovered radioactivity in 1896. Human body contains ~7,000 Bq from potassium-40. One curie = 37 billion becquerels.
Picocurie (pCi)
A picocurie (pCi) equals 10⁻¹² curie or 0.037 Bq. Standard US unit for radon: EPA action level is 4 pCi/L. Drinking water: 15 pCi/L alpha limit. One pCi = 2.22 decays per minute. Used extensively in US environmental regulations.
