Formula
Formula
Bq = pCi × 0.037
Multiply any value in picocuries by 0.037 to obtain the value in becquerels.
Worked example
Convert 100 pCi to Bq.
- 01Start with 100 pCi.
- 02Multiply by the conversion factor: 100 × 0.037 = 3.7 Bq.
Result100 pCi = 3.7 Bq

FAQ
What is the conversion factor from pCi to Bq?
1 pCi equals 0.037 Bq. To convert, multiply the value in picocuries by 0.037.
How do I convert 1 pCi to Bq?
1 pCi = 0.037 Bq. For any value, multiply by 0.037.
How do I convert Bq back to pCi?
Divide by the same factor — or equivalently, multiply by 27.02703. So 1 Bq = 27.027 pCi.
When would I need to convert picocurie to becquerel?
Radioactivity (activity) conversions between pCi and Bq are routine in health physics, nuclear medicine ordering, environmental monitoring, radiopharmacy and reactor/accelerator-source documentation. The becquerel (Bq) is the SI unit; the curie (Ci) is the legacy unit (1 Ci ≡ 3.7×10¹⁰ Bq exactly). This category is strictly activity (decays per second) — it does NOT cover absorbed dose (Gy, rad), dose equivalent (Sv, rem), exposure or dose rate, all of which are different physical quantities and live in separate categories.
Is the conversion exact?
The factor shown is precise to at least 7 significant figures. For most process-engineering work this is far better than instrument accuracy. For metrology or trade applications, refer to the relevant national standard (NIST, BIPM, ISO 80000).
