Convert Femtobecquerels to Exabecquerels
Convert Femtobecquerels (fBq) to Exabecquerels (EBq) instantly and accurately.
Conversion Formula
EBq = fBq × 1.000000000e-33
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 Exabecquerels
The exabecquerel (EBq) equals 10¹⁸ Bq. The global inventory of ⁴⁰K in the Earth's oceans is ~17 EBq; atmospheric nuclear weapons testing (1945-1963) deposited ~2 EBq of ¹⁴C globally; total natural radioactivity in the human body worldwide sums to ~10 EBq. 1 EBq = 10¹⁸ Bq = 10³ PBq.
