Convert Kilofarads to Femtofarads
Convert Kilofarads (kF) to Femtofarads (fF) instantly and accurately.
Conversion Formula
fF = kF × 1.000000000e+18
About Kilofarads
The kilofarad (kF) equals 10³ F, reached only by large supercapacitor assemblies for energy buffering. Industrial supercapacitor modules for tram and metro regenerative braking are rated 500-10 000 F = 0.5-10 kF; hybrid-bus energy buffers stack 3 000 F cells to achieve several kilofarads; grid fast-response voltage-stabilisation banks are discussed in the kilofarad range. 1 kF = 10³ F = 10⁻³ MF.
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.
