kilocoulomb to milliampere-hour
Convert kilocoulomb (kC) to milliampere-hour (mAh). Use an editable electric charge converter, conversion formula, and reference table.
1 kC = 277.7777778 mAh
Conversion formula
One kilocoulomb equals 277.7777778 milliampere-hour. Multiply your value in kilocoulomb by this factor to get milliampere-hour. For the reverse conversion, divide by the same factor.
Worked example
To convert 5 kilocoulomb:5 × 277.7777778 = 1,388.888889 mAh

About these measurements
Electric charge can be expressed in coulombs or ampere-hours.
The base reference used here is the coulomb. One kilocoulomb is 1,000 base units; one milliampere-hour is 3.6 base units.
Important distinctions
Ampere-hours are charge, not energy. Battery voltage is needed to calculate watt-hours.
Precision
The converter uses stored conversion factors and floating-point arithmetic. Results display up to ten significant digits, switching to scientific notation for very small or large values. Keep the precision of your original measurement when reporting results.
Common questions
How do I convert kC to mAh?
