Conversion Formula
GF = aF × 1.000000000e-27
About Attofarads
The attofarad (aF) equals 10⁻¹⁸ F, the scale for quantum-mechanical and nanoscale capacitances. Carbon-nanotube transistor gate capacitances are 1-100 aF; single-electron tunnel junctions in Coulomb-blockade devices operate in the attofarad range; scanning-probe microscopy tip-sample junctions at sub-nanometre separation approach 1 aF. 1 aF = 10⁻³ fF = 10⁻¹⁸ F.
About Gigafarads
The gigafarad (GF) equals 10⁹ F, numerically identical to the CGS-EMU abfarad. No physical capacitor approaches 1 GF; the value arises in theoretical superconducting circuit analysis and in historical CGS-EMU electromagnetic texts where the abfarad (= 1 GF) was the natural capacitance unit. 1 GF = 10³ MF = 10⁹ F = 1 abF.
