Ampere-Hour to Coulomb (Ah to C)
Convert Ah to C — Electric Charge converter
One ampere-hour equals 3600 C, so to convert ampere-hours to coulombs you multiply the value by 3600. A ampere-hour is larger than a coulomb — going the other way, 1 C = 0.0002777778 Ah. For example, 10 Ah = 36000 C and 50 Ah = 180000 C.
