FAQ
What is the conversion factor from kC to mA·h?
1 kC equals 277.7778 mA·h. To convert, multiply the value in kilocoulombs by 277.7778.
How do I convert 1 kC to mA·h?
1 kC = 277.778 mA·h. For any value, multiply by 277.7778.
How do I convert mA·h back to kC?
Divide by the same factor — or equivalently, multiply by 0.0036. So 1 mA·h = 0.0036 kC.
When would I need to convert kilocoulomb to milliampere-hour?
Electric-charge conversions between kC and mA·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).
