About Converting Femtofarads to Nanofarads
Femtofarad and Nanofarad 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: Femtofarad is 1e-15 farad units, and nanofarad is 1e-9 farad units.
Formula
nanofarads = femtofarads × 0.000001
This factor comes from each unit's defined relationship to the category's base unit: 1 femtofarad equals 1e-15 base units, and 1 nanofarad equals 1e-9 base units, so dividing one by the other gives the direct femtofarad-to-nanofarad factor of 0.000001.
Simple example
1 fF × 0.000001 = 0.000001 nF
1 femtofarad = 0.000001 nanofarads.
Real-world example
120 fF × 0.000001 = 0.00012 nF
120 femtofarads = 0.00012 nanofarads.

Reverse conversion: Nanofarad to Femtofarad
0.000001 nF × 1000000 = 1 fF
0.000001 nanofarads = 1 femtofarad.
femtofarads = nanofarads × 1000000

Frequently asked questions
How many nanofarads are in 1 femtofarad?
1 femtofarad equals 0.000001 nanofarads, using the exact defined conversion factor rather than an estimate.
How do I convert femtofarad to nanofarad?
Multiply the femtofarad value by 0.000001. The converter above does this instantly to whatever precision you set.
How do I convert nanofarad back to femtofarad?
Use the reverse factor: 1 nanofarad equals 1,000,000 femtofarads. You can also use the swap control in the converter above to flip the direction instantly.
What is a femtofarad?
Femtofarad (fF) is a unit of electricity.
What is a nanofarad?
Nanofarad (nF) is a unit of electricity.
Is the femtofarad to nanofarad conversion exact?
Yes. Both femtofarad and nanofarad are defined by fixed standards rather than physical artifacts, so the factor of 0.000001 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.
