About Converting Nanoohms to Femtoohms
Nanoohm and Femtoohm 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: Nanoohm is 1e-9 ohm units, and femtoohm is 1e-15 ohm units.
Formula
femtoohms = nanoohms × 1000000
This factor comes from each unit's defined relationship to the category's base unit: 1 nanoohm equals 1e-9 base units, and 1 femtoohm equals 1e-15 base units, so dividing one by the other gives the direct nanoohm-to-femtoohm factor of 1000000.
Simple example
1 nOhm × 1000000 = 1,000,000 fOhm
1 nanoohm = 1,000,000 femtoohms.
Real-world example
120 nOhm × 1000000 = 120,000,000 fOhm
120 nanoohms = 120,000,000 femtoohms.

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

Frequently asked questions
How many femtoohms are in 1 nanoohm?
1 nanoohm equals 1,000,000 femtoohms, using the exact defined conversion factor rather than an estimate.
How do I convert nanoohm to femtoohm?
Multiply the nanoohm value by 1000000. The converter above does this instantly to whatever precision you set.
How do I convert femtoohm back to nanoohm?
Use the reverse factor: 1 femtoohm equals 0.000001 nanoohms. You can also use the swap control in the converter above to flip the direction instantly.
What is a nanoohm?
Nanoohm (nOhm) is a unit of electricity.
What is a femtoohm?
Femtoohm (fOhm) is a unit of electricity.
Is the nanoohm to femtoohm conversion exact?
Yes. Both nanoohm and femtoohm 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.
