Formula
Formula
pA = μA × 1000000
Multiply any value in microamperes by 1000000 to obtain the value in picoamperes.
Worked example
Convert 1 μA to pA.
- 01Start with 1 μA.
- 02Multiply by the conversion factor: 1 × 1000000 = 1.00000e+6 pA.
Result1 μA = 1.00000e+6 pA

FAQ
What is the conversion factor from μA to pA?
1 μA equals 1000000 pA. To convert, multiply the value in microamperes by 1000000.
How do I convert 1 μA to pA?
1 μA = 1.00000e+6 pA. For any value, multiply by 1000000.
How do I convert pA back to μA?
Divide by the same factor — or equivalently, multiply by 1e-6. So 1 pA = 1e-6 μA.
When would I need to convert microampere to picoampere?
Current conversions between μA and pA 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).
