About the capacitance converter

Capacitance measures a component’s ability to store charge per unit voltage applied, with SI units of farads (F). One farad is enormous, so practical capacitors are rated in microfarads (μF), nanofarads (nF), or picofarads (pF). Power-supply bulk capacitors run into the millifarads, while ceramic decoupling caps live in pF–nF territory. Use this converter to switch between any prefix or the older CGS units (statfarad, abfarad).

Frequently asked questions

  • How big is 1 farad?

    Huge by electronics standards. A 1 F supercapacitor at 5 V stores about 12.5 joules of energy. Most signal-path caps are 8–12 orders of magnitude smaller.

  • How many pF are in 1 μF?

    1,000,000 pF. The chain is 1 F = 1,000 mF = 1,000,000 μF = 10⁹ nF = 10¹² pF.

  • What determines a capacitor’s capacitance?

    C = ε A / d for a parallel-plate cap: dielectric permittivity × plate area, divided by gap. Larger area, thinner gap, and higher-ε dielectric all increase capacitance.
