abF = pF × 1.000000000e-21
About Picofarads
The picofarad (pF) equals 10⁻¹² F, the everyday unit for small-signal capacitors in RF and high-frequency circuits. Ceramic chip capacitors range from 0.5 to 100 pF; crystal oscillator load capacitance is typically 12-22 pF; PCB trace-to-trace coupling is 0.1-10 pF/cm; the human body presents roughly 100 pF at radio frequencies. 1 pF = 10⁻³ nF = 10⁻¹² F.
About Abfarads
The abfarad (abF) is the capacitance unit of the CGS-EMU system, equal to 1 abC / 1 abV = 10 C / 10⁻⁸ V = 10⁹ F, exactly equal to 1 GF in SI. It appeared in nineteenth-century and early twentieth-century electromagnetic engineering texts alongside abohms and abamperes; 1 abF represents the capacitance of a connection storing 10 C at 10 nV. 1 abF = 10⁹ F = 1 GF.
