Context values
Some unit families need one extra value for a physically accurate result.
Milliampere is 0.001 ampere units.
Result = input x 1e-9 / 0.001.

About Converting Nanoamperes to Milliamperes
Nanoampere and Milliampere 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 milliampere is 0.001 ampere units.
Formula
milliamperes = nanoamperes × 0.000001
This factor comes from each unit's defined relationship to the category's base unit: 1 nanoampere equals 1e-9 base units, and 1 milliampere equals 0.001 base units, so dividing one by the other gives the direct nanoampere-to-milliampere factor of 0.000001.
Simple example
1 nA × 0.000001 = 0.000001 mA
1 nanoampere = 0.000001 milliamperes.
Real-world example
120 nA × 0.000001 = 0.00012 mA
120 nanoamperes = 0.00012 milliamperes.

Reverse conversion: Milliampere to Nanoampere
0.000001 mA × 1000000 = 1 nA
0.000001 milliamperes = 1 nanoampere.
nanoamperes = milliamperes × 1000000

Frequently asked questions
How many milliamperes are in 1 nanoampere?
1 nanoampere equals 0.000001 milliamperes, using the exact defined conversion factor rather than an estimate.
How do I convert nanoampere to milliampere?
Multiply the nanoampere value by 0.000001. The converter above does this instantly to whatever precision you set.
How do I convert milliampere back to nanoampere?
Use the reverse factor: 1 milliampere equals 1,000,000 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 milliampere?
Milliampere (mA) is a unit of electricity.
Is the nanoampere to milliampere conversion exact?
Yes. Both nanoampere and milliampere 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.
