About Converting Femtohenrys to Nanohenrys
Femtohenry and Nanohenry 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 nanohenry is 1e-9 henry units.
Formula
nanohenrys = femtohenrys × 0.000001
This factor comes from each unit's defined relationship to the category's base unit: 1 femtohenry equals 1e-15 base units, and 1 nanohenry equals 1e-9 base units, so dividing one by the other gives the direct femtohenry-to-nanohenry factor of 0.000001.
Simple example
1 fH × 0.000001 = 0.000001 nH
1 femtohenry = 0.000001 nanohenrys.
Real-world example
120 fH × 0.000001 = 0.00012 nH
120 femtohenrys = 0.00012 nanohenrys.

Frequently asked questions
How many nanohenrys are in 1 femtohenry?
1 femtohenry equals 0.000001 nanohenrys, using the exact defined conversion factor rather than an estimate.
How do I convert femtohenry to nanohenry?
Multiply the femtohenry value by 0.000001. The converter above does this instantly to whatever precision you set.
How do I convert nanohenry back to femtohenry?
Use the reverse factor: 1 nanohenry equals 1,000,000 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 nanohenry?
Nanohenry (nH) is a unit of electricity.
Is the femtohenry to nanohenry conversion exact?
Yes. Both femtohenry and nanohenry 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.
