Rendered to 6 significant figures.
Formula
Formula
kBq = pCi × 3.7e-5
Multiply any value in picocuries by 3.7e-5 to obtain the value in kilobecquerels.
Worked example
Convert 100000 pCi to kBq.
- 01Start with 100000 pCi.
- 02Multiply by the conversion factor: 100000 × 3.7e-5 = 3.7 kBq.
Result100000 pCi = 3.7 kBq

FAQ
What is the conversion factor from pCi to kBq?
1 pCi equals 3.7e-5 kBq. To convert, multiply the value in picocuries by 3.7e-5.
How do I convert 1 pCi to kBq?
1 pCi = 3.7e-5 kBq. For any value, multiply by 3.7e-5.
How do I convert kBq back to pCi?
Divide by the same factor — or equivalently, multiply by 27027.03. So 1 kBq = 27027 pCi.
When would I need to convert picocurie to kilobecquerel?
Radioactivity (activity) conversions between pCi and kBq 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).
