About Converting Nanohenrys to Femtohenrys
Nanohenry 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: Nanohenry is 1e-9 henry units, and femtohenry is 1e-15 henry units.
Formula
femtohenrys = nanohenrys × 1000000
This factor comes from each unit's defined relationship to the category's base unit: 1 nanohenry equals 1e-9 base units, and 1 femtohenry equals 1e-15 base units, so dividing one by the other gives the direct nanohenry-to-femtohenry factor of 1000000.
Simple example
1 nH × 1000000 = 1,000,000 fH
1 nanohenry = 1,000,000 femtohenrys.
Real-world example
120 nH × 1000000 = 120,000,000 fH
120 nanohenrys = 120,000,000 femtohenrys.

Reverse conversion: Femtohenry to Nanohenry
1 fH × 0.000001 = 0.000001 nH
1 femtohenry = 0.000001 nanohenrys.
nanohenrys = femtohenrys × 0.000001

Frequently asked questions
How many femtohenrys are in 1 nanohenry?
1 nanohenry equals 1,000,000 femtohenrys, using the exact defined conversion factor rather than an estimate.
How do I convert nanohenry to femtohenry?
Multiply the nanohenry value by 1000000. The converter above does this instantly to whatever precision you set.
How do I convert femtohenry back to nanohenry?
Use the reverse factor: 1 femtohenry equals 0.000001 nanohenrys. You can also use the swap control in the converter above to flip the direction instantly.
What is a nanohenry?
Nanohenry (nH) is a unit of electricity.
What is a femtohenry?
Femtohenry (fH) is a unit of electricity.
Is the nanohenry to femtohenry conversion exact?
Yes. Both nanohenry and femtohenry are defined by fixed standards rather than physical artifacts, so the factor of 1000000 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.
