Formula
Formula
pC = C × 1e+12
Multiply any value in coulombs by 1e+12 to obtain the value in picocoulombs.
Worked example
Convert 1 C to pC.
- 01Start with 1 C.
- 02Multiply by the conversion factor: 1 × 1e+12 = 1e+12 pC.
Result1 C = 1e+12 pC

FAQ
What is the conversion factor from C to pC?
1 C equals 1e+12 pC. To convert, multiply the value in coulombs by 1e+12.
How do I convert 1 C to pC?
1 C = 1e+12 pC. For any value, multiply by 1e+12.
How do I convert pC back to C?
Divide by the same factor — or equivalently, multiply by 1e-12. So 1 pC = 1e-12 C.
When would I need to convert coulomb to picocoulomb?
Electric-charge conversions between C and pC appear in battery capacity specification (A·h, mA·h), electroplating and electrochemistry (coulombs of charge transferred), and capacitor energy calculations. 1 A·h is exactly 3600 C — the conversion is a linear factor and does not depend on voltage, current profile or chemistry.
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).
