FAQ
What is the conversion factor from pC to A·h?
1 pC equals 2.777778e-16 A·h. To convert, multiply the value in picocoulombs by 2.777778e-16.
How do I convert 1 pC to A·h?
1 pC = 2.77778e-16 A·h. For any value, multiply by 2.777778e-16.
How do I convert A·h back to pC?
Divide by the same factor — or equivalently, multiply by 3.6e+15. So 1 A·h = 3.6e+15 pC.
When would I need to convert picocoulomb to ampere-hour?
Electric-charge conversions between pC and A·h 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).
