About Converting Nanosiemens to Femtosiemens
Nanosiemens and Femtosiemens 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: Nanosiemens is 1e-9 siemens units, and femtosiemens is 1e-15 siemens units.
Formula
femtosiemens = nanosiemens × 1000000
This factor comes from each unit's defined relationship to the category's base unit: 1 nanosiemens equals 1e-9 base units, and 1 femtosiemens equals 1e-15 base units, so dividing one by the other gives the direct nanosiemens-to-femtosiemens factor of 1000000.
Simple example
1 nS × 1000000 = 1,000,000 fS
1 nanosiemens = 1,000,000 femtosiemens.
Real-world example
120 nS × 1000000 = 120,000,000 fS
120 nanosiemens = 120,000,000 femtosiemens.
Conversion table
| Nanosiemens (nS) | Femtosiemens (fS) |
|---|---|
| 1 nS | 1,000,000 fS |
| 5 nS | 5,000,000 fS |
| 12 nS | 12,000,000 fS |
| 24 nS | 24,000,000 fS |
| 120 nS | 120,000,000 fS |
| 240 nS | 240,000,000 fS |
Reverse conversion: Femtosiemens to Nanosiemens
1 fS × 0.000001 = 0.000001 nS
1 femtosiemens = 0.000001 nanosiemens.
nanosiemens = femtosiemens × 0.000001

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