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