FAQ
What is the conversion factor from nCi to Bq?
1 nCi equals 37 Bq. To convert, multiply the value in nanocuries by 37.
How do I convert 1 nCi to Bq?
1 nCi = 37 Bq. For any value, multiply by 37.
How do I convert Bq back to nCi?
Divide by the same factor — or equivalently, multiply by 0.02702703. So 1 Bq = 0.027027 nCi.
When would I need to convert nanocurie to becquerel?
Radioactivity (activity) conversions between nCi 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).
