About Converting Picoamperes to Nanoamperes
Picoampere 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: Picoampere is 1e-12 ampere units, and nanoampere is 1e-9 ampere units.
Formula
nanoamperes = picoamperes × 0.001
This factor comes from each unit's defined relationship to the category's base unit: 1 picoampere equals 1e-12 base units, and 1 nanoampere equals 1e-9 base units, so dividing one by the other gives the direct picoampere-to-nanoampere factor of 0.001.
Simple example
1 pA × 0.001 = 0.001 nA
1 picoampere = 0.001 nanoamperes.
Real-world example
120 pA × 0.001 = 0.12 nA
120 picoamperes = 0.12 nanoamperes.

Reverse conversion: Nanoampere to Picoampere
0.001 nA × 1000 = 1 pA
0.001 nanoamperes = 1 picoamperes.
picoamperes = nanoamperes × 1000

Frequently asked questions
How many nanoamperes are in 1 picoampere?
1 picoampere equals 0.001 nanoamperes, using the exact defined conversion factor rather than an estimate.
How do I convert picoampere to nanoampere?
Multiply the picoampere value by 0.001. The converter above does this instantly to whatever precision you set.
How do I convert nanoampere back to picoampere?
Use the reverse factor: 1 nanoampere equals 1,000 picoamperes. You can also use the swap control in the converter above to flip the direction instantly.
What is a picoampere?
Picoampere (pA) is a unit of electricity.
What is a nanoampere?
Nanoampere (nA) is a unit of electricity.
Is the picoampere to nanoampere conversion exact?
Yes. Both picoampere and nanoampere are defined by fixed standards rather than physical artifacts, so the factor of 0.001 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.
