About these measurements

Electric charge can be expressed in coulombs or ampere-hours.

The base reference used here is the coulomb. One hectocoulomb is 100 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
