FAQ
What is the conversion factor from nCi to pCi?
1 nCi equals 1000 pCi. To convert, multiply the value in nanocuries by 1000.
How do I convert 1 nCi to pCi?
1 nCi = 1000 pCi. For any value, multiply by 1000.
How do I convert pCi back to nCi?
Divide by the same factor — or equivalently, multiply by 0.001. So 1 pCi = 0.001 nCi.
When would I need to convert nanocurie to picocurie?
Radioactivity (activity) conversions between nCi 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).
