About Converting Petaamperes to Nanoamperes
Petaampere 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: Petaampere is 1000000000000000 ampere units, and nanoampere is 1e-9 ampere units.
Formula
nanoamperes = petaamperes × 1e+24
This factor comes from each unit's defined relationship to the category's base unit: 1 petaampere equals 1e+15 base units, and 1 nanoampere equals 1e-9 base units, so dividing one by the other gives the direct petaampere-to-nanoampere factor of 1e+24.
Simple example
1 PA × 1e+24 = 1e+24 nA
1 petaampere = 1e+24 nanoamperes.
Real-world example
120 PA × 1e+24 = 1.2e+26 nA
120 petaamperes = 1.2e+26 nanoamperes.

Reverse conversion: Nanoampere to Petaampere
1e+24 nA × 1e-24 = 1 PA
1e+24 nanoamperes = 1 petaampere.
petaamperes = nanoamperes × 1e-24

Frequently asked questions
How many nanoamperes are in 1 petaampere?
1 petaampere equals 1e+24 nanoamperes, using the exact defined conversion factor rather than an estimate.
How do I convert petaampere to nanoampere?
Multiply the petaampere value by 1e+24. The converter above does this instantly to whatever precision you set.
How do I convert nanoampere back to petaampere?
Use the reverse factor: 1 nanoampere equals 1e-24 petaamperes. You can also use the swap control in the converter above to flip the direction instantly.
What is a petaampere?
Petaampere (PA) is a unit of electricity.
What is a nanoampere?
Nanoampere (nA) is a unit of electricity.
Is the petaampere to nanoampere conversion exact?
Yes. Both petaampere and nanoampere are defined by fixed standards rather than physical artifacts, so the factor of 1e+24 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.
