Abfarad Converter

Convert abfarads to farads, microfarads, nanofarads, picofarads, statfarads and other capacitance units.

What this tool does

Convert abfarads to farads, microfarads, nanofarads, picofarads, statfarads and other capacitance units. Type an amount in abfarads (EMU of capacitance), choose the units, and the tool converts it to farads. 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 Abfarad (EMU of capacitance).
  • To: Choose one of the same 8 units as "From". Starts as Farad.

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 abfarads (EMU of capacitance) to farads:

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

Multiply the number of abfarads (EMU of capacitance) by 1,000,000,000 to get farads. Both units are exact definitions, so 1,000,000,000 is the exact factor: 1 abF = 1,000,000,000 F.

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 farads is one abfarad?
A: One abfarad is 1,000,000,000 farads (10⁹ F). It is the capacitance unit of the CGS electromagnetic system.
Q: What is the difference between an abfarad and a statfarad?
A: The abfarad belongs to the electromagnetic CGS system and the statfarad to the electrostatic CGS system. A statfarad is about 1.1127 × 10⁻¹² farad, so one abfarad is vastly larger.
Q: Can I convert from farads to abfarads?
A: Yes. Choose farad in the From box and abfarad in the To box.
