About Converting Femtofarads to Picofarads
Femtofarad and Picofarad 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 picofarad is 1e-12 farad units.
Formula
picofarads = femtofarads × 0.001
This factor comes from each unit's defined relationship to the category's base unit: 1 femtofarad equals 1e-15 base units, and 1 picofarad equals 1e-12 base units, so dividing one by the other gives the direct femtofarad-to-picofarad factor of 0.001.
Simple example
1 fF × 0.001 = 0.001 pF
1 femtofarad = 0.001 picofarads.
Real-world example
120 fF × 0.001 = 0.12 pF
120 femtofarads = 0.12 picofarads.

Reverse conversion: Picofarad to Femtofarad
0.001 pF × 1000 = 1 fF
0.001 picofarads = 1 femtofarad.
femtofarads = picofarads × 1000

Frequently asked questions
How many picofarads are in 1 femtofarad?
1 femtofarad equals 0.001 picofarads, using the exact defined conversion factor rather than an estimate.
How do I convert femtofarad to picofarad?
Multiply the femtofarad value by 0.001. The converter above does this instantly to whatever precision you set.
How do I convert picofarad back to femtofarad?
Use the reverse factor: 1 picofarad equals 1,000 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 picofarad?
Picofarad (pF) is a unit of electricity.
Is the femtofarad to picofarad conversion exact?
Yes. Both femtofarad and picofarad are defined by fixed standards rather than physical artifacts, so the factor of 0.001 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.
