Convert Femtobecquerels to Picocuries
Convert Femtobecquerels (fBq) to Picocuries (pCi) instantly and accurately.
Conversion Formula
pCi = fBq × 2.702702703e-14
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.
About Picocuries
The picocurie (pCi) equals 3.7 × 10⁻² Bq = 37 mBq. The US EPA uses pCi/L as the standard unit for indoor radon (action level: 4 pCi/L) and drinking water radon; NRC licence exemption thresholds and natural uranium activity in groundwater are expressed in pCi/L. 1 pCi = 3.7 × 10⁻² Bq.
