Conversion Formula
MF = fF × 1.000000000e-21
About Femtofarads
The femtofarad (fF) equals 10⁻¹⁵ F, the standard unit for transistor gate capacitances in CMOS technology and MEMS sensors. Transistors in 7 nm process nodes have gate capacitances of 0.5-5 fF; MEMS capacitive pressure sensors use sense-gap capacitances of 1-100 fF; integrated-circuit bond-pad parasitics and via coupling are quantified in femtofarads. 1 fF = 10⁻³ pF = 10⁻¹⁵ 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.
