Capacitance Converter — Farads, µF, nF & pF

Convert between farads, millifarads, microfarads, nanofarads, and picofarads.

—
How this conversion works. Every unit is converted through the farad using exact SI prefixes; CGS units use factors from NIST Special Publication 811.

How to use

  1. Choose the units to convert from and to.
  2. Enter a value — the converted result updates instantly.

Frequently asked questions

How do I convert microfarad to nanofarad?

1 microfarad = 1000 nanofarad. Choose "Microfarad (µF)" as From and "Nanofarad (nF)" as To, type a value, and the result updates instantly.

How do I read a capacitor marked 104?

Three-digit codes give picofarads: first two digits × 10^third. 104 = 10 × 10⁴ pF = 100,000 pF = 100 nF = 0.1 µF.

Why are real capacitors never a full farad?

A farad is enormous for electrostatics — typical circuit values run pF to µF. Supercapacitors are the exception, reaching hundreds of farads at low voltage.

Is my data sent to a server?

No. Conversions run entirely in your browser using fixed factors — nothing is uploaded or logged.
