Formula
Formula
mA = pA × 1e-9
Multiply any value in picoamperes by 1e-9 to obtain the value in milliamperes.
Worked example
Convert 1e+9 pA to mA.
- 01Start with 1e+9 pA.
- 02Multiply by the conversion factor: 1e+9 × 1e-9 = 1 mA.
Result1e+9 pA = 1 mA

FAQ
What is the conversion factor from pA to mA?
1 pA equals 1e-9 mA. To convert, multiply the value in picoamperes by 1e-9.
How do I convert 1 pA to mA?
1 pA = 1e-9 mA. For any value, multiply by 1e-9.
How do I convert mA back to pA?
Divide by the same factor — or equivalently, multiply by 1e+9. So 1 mA = 1e+9 pA.
When would I need to convert picoampere to milliampere?
Current conversions between pA and mA appear in motor and cable sizing, instrumentation loop design (4–20 mA), battery characterisation and electronics. Amperes are standard for power circuits; milliamperes and microamperes are the working units for signal conditioning and sensor outputs.
Is the conversion exact?
The factor shown is precise to at least 7 significant figures. For most process-engineering work this is far better than instrument accuracy. For metrology or trade applications, refer to the relevant national standard (NIST, BIPM, ISO 80000).
