About Converting Femtoamperes to Nanoamperes
Femtoampere and Nanoampere 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: Femtoampere is 1e-15 ampere units, and nanoampere is 1e-9 ampere units.
Formula
nanoamperes = femtoamperes × 0.000001
This factor comes from each unit's defined relationship to the category's base unit: 1 femtoampere equals 1e-15 base units, and 1 nanoampere equals 1e-9 base units, so dividing one by the other gives the direct femtoampere-to-nanoampere factor of 0.000001.
Simple example
1 fA × 0.000001 = 0.000001 nA
1 femtoampere = 0.000001 nanoamperes.
Real-world example
120 fA × 0.000001 = 0.00012 nA
120 femtoamperes = 0.00012 nanoamperes.

Reverse conversion: Nanoampere to Femtoampere
0.000001 nA × 1000000 = 1 fA
0.000001 nanoamperes = 1 femtoampere.
femtoamperes = nanoamperes × 1000000

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