Formula
Formula
kC = A·h × 3.6
Multiply any value in ampere-hours by 3.6 to obtain the value in kilocoulombs.
Worked example
Convert 1000 A·h to kC.
- 01Start with 1000 A·h.
- 02Multiply by the conversion factor: 1000 × 3.6 = 3600 kC.
Result1000 A·h = 3600 kC

FAQ
What is the conversion factor from A·h to kC?
1 A·h equals 3.6 kC. To convert, multiply the value in ampere-hours by 3.6.
How do I convert 1 A·h to kC?
1 A·h = 3.6 kC. For any value, multiply by 3.6.
How do I convert kC back to A·h?
Divide by the same factor — or equivalently, multiply by 0.2777778. So 1 kC = 0.277778 A·h.
When would I need to convert ampere-hour to kilocoulomb?
Electric-charge conversions between A·h and kC 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).
