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 Megafarads
The megafarad (MF) equals 10⁶ F, a scale not reached by any discrete capacitor available today. Theoretical projections of utility-scale ultracapacitor arrays for grid energy storage discuss megafarad totals; the Earth-ionosphere spherical capacitor is estimated at about 0.9 F, so MF is well beyond any natural or engineered capacitor at present. 1 MF = 10³ kF = 10⁶ F.
