About Converting Exafarads to Gigafarads
Exafarad and Gigafarad both belong to the electricity family — voltage, current, resistance, power, or energy — units that show up constantly when working across the different standards used by household wiring (120V/240V depending on region), automotive electrical systems (12V/24V), and electronics design. Specifically: Exafarad is 1000000000000000000 farad units, and gigafarad is 1000000000 farad units.
Formula
gigafarads = exafarads × 1000000000
This factor comes from each unit's defined relationship to the category's base unit: 1 exafarad equals 1e+18 base units, and 1 gigafarad equals 1000000000 base units, so dividing one by the other gives the direct exafarad-to-gigafarad factor of 1000000000.
Simple example
1 EF × 1000000000 = 1,000,000,000 GF
1 exafarad = 1,000,000,000 gigafarads.
Real-world example
120 EF × 1000000000 = 120,000,000,000 GF
120 exafarads = 120,000,000,000 gigafarads.

Frequently asked questions
How many gigafarads are in 1 exafarad?
1 exafarad equals 1,000,000,000 gigafarads, using the exact defined conversion factor rather than an estimate.
How do I convert exafarad to gigafarad?
Multiply the exafarad value by 1000000000. The converter above does this instantly to whatever precision you set.
How do I convert gigafarad back to exafarad?
Use the reverse factor: 1 gigafarad equals 1e-9 exafarads. You can also use the swap control in the converter above to flip the direction instantly.
What is a exafarad?
Exafarad (EF) is a unit of electricity.
What is a gigafarad?
Gigafarad (GF) is a unit of electricity.
Is the exafarad to gigafarad conversion exact?
Yes. Both exafarad and gigafarad are defined by fixed standards rather than physical artifacts, so the factor of 1000000000 used above is exact to as many digits as you choose to display.
What's the difference between voltage, current, and resistance?
Voltage (volts) is the electrical potential difference driving current through a circuit. Current (amperes) is the rate of flow of electric charge. Resistance (ohms) is how much a component opposes that flow. They're related by Ohm's law (V = I × R), but they are distinct physical quantities, and this page converts between units of just one of them.
