About Converting Femtohenrys to Picohenrys
Femtohenry and Picohenry 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: Femtohenry is 1e-15 henry units, and picohenry is 1e-12 henry units.
Formula
picohenrys = femtohenrys × 0.001
This factor comes from each unit's defined relationship to the category's base unit: 1 femtohenry equals 1e-15 base units, and 1 picohenry equals 1e-12 base units, so dividing one by the other gives the direct femtohenry-to-picohenry factor of 0.001.
Simple example
1 fH × 0.001 = 0.001 pH
1 femtohenry = 0.001 picohenrys.
Real-world example
120 fH × 0.001 = 0.12 pH
120 femtohenrys = 0.12 picohenrys.

Reverse conversion: Picohenry to Femtohenry
0.001 pH × 1000 = 1 fH
0.001 picohenrys = 1 femtohenry.
femtohenrys = picohenrys × 1000

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