In other words, it's a unit of measure of the rate of electron flow in an electrical conductor. One ampere equals one coulomb of electrical charge. Use our online ampere calculator to convert values from horsepower/kilowatts/kilovolts amps to ampere. Amp calculation is done by selecting the conversion, phase type, followed by entering the Kilovolt-ampere and voltage.
