About Converting Femtoohms to Nanoohms
Femtoohm and Nanoohm 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: Femtoohm is 1e-15 ohm units, and nanoohm is 1e-9 ohm units.
Formula
nanoohms = femtoohms × 0.000001
This factor comes from each unit's defined relationship to the category's base unit: 1 femtoohm equals 1e-15 base units, and 1 nanoohm equals 1e-9 base units, so dividing one by the other gives the direct femtoohm-to-nanoohm factor of 0.000001.
Simple example
1 fOhm × 0.000001 = 0.000001 nOhm
1 femtoohm = 0.000001 nanoohms.
Real-world example
120 fOhm × 0.000001 = 0.00012 nOhm
120 femtoohms = 0.00012 nanoohms.

Reverse conversion: Nanoohm to Femtoohm
0.000001 nOhm × 1000000 = 1 fOhm
0.000001 nanoohms = 1 femtoohm.
femtoohms = nanoohms × 1000000

Frequently asked questions
How many nanoohms are in 1 femtoohm?
1 femtoohm equals 0.000001 nanoohms, using the exact defined conversion factor rather than an estimate.
How do I convert femtoohm to nanoohm?
Multiply the femtoohm value by 0.000001. The converter above does this instantly to whatever precision you set.
How do I convert nanoohm back to femtoohm?
Use the reverse factor: 1 nanoohm equals 1,000,000 femtoohms. You can also use the swap control in the converter above to flip the direction instantly.
What is a femtoohm?
Femtoohm (fOhm) is a unit of electricity.
What is a nanoohm?
Nanoohm (nOhm) is a unit of electricity.
Is the femtoohm to nanoohm conversion exact?
Yes. Both femtoohm and nanoohm 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.
