Rendered to 6 significant figures.
Formula
Formula
A = pA × 1e-12
Multiply any value in picoamperes by 1e-12 to obtain the value in amperes.
Worked example
Convert 1e+12 pA to A.
- 01Start with 1e+12 pA.
- 02Multiply by the conversion factor: 1e+12 × 1e-12 = 1 A.
Result1e+12 pA = 1 A

FAQ
What is the conversion factor from pA to A?
1 pA equals 1e-12 A. To convert, multiply the value in picoamperes by 1e-12.
How do I convert 1 pA to A?
1 pA = 1e-12 A. For any value, multiply by 1e-12.
How do I convert A back to pA?
Divide by the same factor — or equivalently, multiply by 1e+12. So 1 A = 1e+12 pA.
When would I need to convert picoampere to ampere?
Current conversions between pA and A 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).
