About Converting Picohenrys to Femtohenrys
Picohenry and Femtohenry 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: Picohenry is 1e-12 henry units, and femtohenry is 1e-15 henry units.
Formula
femtohenrys = picohenrys × 1000
This factor comes from each unit's defined relationship to the category's base unit: 1 picohenry equals 1e-12 base units, and 1 femtohenry equals 1e-15 base units, so dividing one by the other gives the direct picohenry-to-femtohenry factor of 1000.
Simple example
1 pH × 1000 = 1,000 fH
1 picohenry = 1,000 femtohenrys.
Real-world example
120 pH × 1000 = 120,000 fH
120 picohenrys = 120,000 femtohenrys.

Frequently asked questions
How many femtohenrys are in 1 picohenry?
1 picohenry equals 1,000 femtohenrys, using the exact defined conversion factor rather than an estimate.
How do I convert picohenry to femtohenry?
Multiply the picohenry value by 1000. The converter above does this instantly to whatever precision you set.
How do I convert femtohenry back to picohenry?
Use the reverse factor: 1 femtohenry equals 0.001 picohenrys. You can also use the swap control in the converter above to flip the direction instantly.
What is a picohenry?
Picohenry (pH) is a unit of electricity.
What is a femtohenry?
Femtohenry (fH) is a unit of electricity.
Is the picohenry to femtohenry conversion exact?
Yes. Both picohenry and femtohenry are defined by fixed standards rather than physical artifacts, so the factor of 1000 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.
