How to Convert Becquerel to Picocurie
- 1 Bq = 27.02702703 pCi
- 1 pCi = 0.037 Bq
- Example: convert 15 Bq to pCi: 15 Bq = 15 × 27.02702703 pCi = 405.4054054 pCi
Formula
pCi = Bq × 27.02702702703
Derivation from SI units:
- 1 Bq = 1 decay per second (s⁻¹).
- 1 pCi = 0.037 Bq.
Both units are defined exactly, so the factor is exact. Becquerel definition: becquerel; Picocurie definition: picocurie.
Worked examples
- A reading of 100 Bq converts to 2702.702703 pCi.
100 Bq × 27.02702703 = 2702.702703 pCi - A value of 3700 Bq is 100000 pCi.
3700 Bq × 27.02702703 = 100000 pCi
