Context values
Some unit families need one extra value for a physically accurate result.
Milliampere is 0.001 ampere units.
Result = input x 1e-12 / 0.001.

About Converting Picoamperes to Milliamperes
Picoampere 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: Picoampere is 1e-12 ampere units, and milliampere is 0.001 ampere units.
Formula
milliamperes = picoamperes × 1e-9
This factor comes from each unit's defined relationship to the category's base unit: 1 picoampere equals 1e-12 base units, and 1 milliampere equals 0.001 base units, so dividing one by the other gives the direct picoampere-to-milliampere factor of 1e-9.
Simple example
1 pA × 1e-9 = 1e-9 mA
1 picoampere = 1e-9 milliamperes.
Real-world example
120 pA × 1e-9 = 1.2e-7 mA
120 picoamperes = 1.2e-7 milliamperes.

Reverse conversion: Milliampere to Picoampere
1e-9 mA × 1000000000 = 1 pA
1e-9 milliamperes = 1 picoamperes.
picoamperes = milliamperes × 1000000000

Frequently asked questions
How many milliamperes are in 1 picoampere?
1 picoampere equals 1e-9 milliamperes, using the exact defined conversion factor rather than an estimate.
How do I convert picoampere to milliampere?
Multiply the picoampere value by 1e-9. The converter above does this instantly to whatever precision you set.
How do I convert milliampere back to picoampere?
Use the reverse factor: 1 milliampere equals 1,000,000,000 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 milliampere?
Milliampere (mA) is a unit of electricity.
Is the picoampere to milliampere conversion exact?
Yes. Both picoampere and milliampere are defined by fixed standards rather than physical artifacts, so the factor of 1e-9 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.
