Farad Converters

Convert farads to millifarads, microfarads, nanofarads, picofarads, femtofarads and other capacitance units.

What this tool does

Convert farads to millifarads, microfarads, nanofarads, picofarads, femtofarads and other capacitance units. Type an amount in farads, choose the units, and the tool converts it to microfarads. It offers 8 capacitance units and also shows the same amount in the others.

Inputs

  • Value: A number.
  • From: Choose one: Farad, Millifarad, Microfarad, Nanofarad, Picofarad, Femtofarad, Abfarad (EMU of capacitance), Statfarad (ESU of capacitance). Starts as Farad.
  • To: Choose one of the same 8 units as "From". Starts as Microfarad.

How to use

  1. Enter the amount you want to convert.
  2. Choose the unit to convert from and the unit to convert to.
  3. Read the result: the converted amount and the same amount in the other units. It appears once every required field has a valid value.

Worked examples

Conversions from farads to microfarads:

  • 1 F = 1,000,000 µF
  • 5 F = 5,000,000 µF
  • 10 F = 10,000,000 µF
  • 50 F = 50,000,000 µF
  • 100 F = 100,000,000 µF

Multiply the number of farads by 1,000,000 to get microfarads. Both units are exact definitions, so 1,000,000 is the exact factor: 1 F = 1,000,000 µF.

Limitations

  • Converts the unit of a capacitance only. It does not work out capacitance from plate area, spacing or dielectric, and it does not combine capacitors in series or parallel.
  • Abfarad and statfarad are historical CGS units, listed for completeness.

FAQs

Q: How many microfarads are in one farad?
A: One farad is 1,000,000 microfarads (10⁶ µF).
Q: Which unit do capacitors use?
A: Most capacitors are labeled in microfarads, nanofarads or picofarads. A farad is a very large amount of capacitance, so values in farads are mostly seen on supercapacitors.
Q: Can I convert the other way?
A: Yes. Swap the From and To units to go from any smaller unit up to farads.
