About Converting Nanoamperes to Centiamperes
Nanoampere and Centiampere 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: Nanoampere is 1e-9 ampere units, and centiampere is 0.01 ampere units.
Formula
centiamperes = nanoamperes × 1e-7
This factor comes from each unit's defined relationship to the category's base unit: 1 nanoampere equals 1e-9 base units, and 1 centiampere equals 0.01 base units, so dividing one by the other gives the direct nanoampere-to-centiampere factor of 1e-7.
Simple example
1 nA × 1e-7 = 1e-7 cA
1 nanoampere = 1e-7 centiamperes.
Real-world example
120 nA × 1e-7 = 0.000012 cA
120 nanoamperes = 0.000012 centiamperes.

Frequently asked questions
How many centiamperes are in 1 nanoampere?
1 nanoampere equals 1e-7 centiamperes, using the exact defined conversion factor rather than an estimate.
How do I convert nanoampere to centiampere?
Multiply the nanoampere value by 1e-7. The converter above does this instantly to whatever precision you set.
How do I convert centiampere back to nanoampere?
Use the reverse factor: 1 centiampere equals 10,000,000 nanoamperes. You can also use the swap control in the converter above to flip the direction instantly.
What is a nanoampere?
Nanoampere (nA) is a unit of electricity.
What is a centiampere?
Centiampere (cA) is a unit of electricity.
Is the nanoampere to centiampere conversion exact?
Yes. Both nanoampere and centiampere are defined by fixed standards rather than physical artifacts, so the factor of 1e-7 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.
