Convert Nanocuries to Femtobecquerels
Convert Nanocuries (nCi) to Femtobecquerels (fBq) instantly and accurately.
Conversion Formula
fBq = nCi × 3.700000000e+16
About Nanocuries
The nanocurie (nCi) equals 37 Bq. Sealed radioactive sources in laboratory instruments (electron-capture detectors in GC, ionisation chambers) are licensed in nCi; nCi is the working unit on US NRC licence forms and instrument calibration certificates for low-level sources. 1 nCi = 37 Bq = 3.7 × 10⁻⁸ Ci.
About Femtobecquerels
The femtobecquerel (fBq) equals 10⁻¹⁵ Bq, used in accelerator mass spectrometry (AMS) to quantify cosmogenic radionuclides (¹⁰Be, ³⁶Cl) in ice cores and geological samples. Ultra-low-background counting in deep underground laboratories reaches the fBq/kg level for solar neutrino detector purity assessment. 1 fBq = 10⁻¹⁵ Bq = 10⁻³ pBq.
