Q:

# How do you convert amps to kVA?

A:

In order to convert amps, short for amperes, into kVA (Kilovolt-ampere), current in amps and the voltage in volts has to be multiplied and then divided by 1000. Mathematically, kVA = Current (in amp) * Voltage (in volts) / 1000.

An amp is a unit of electric current, while a kVA (Kilovolt-ampere) is a unit of apparent power of an electrical circuit; hence it's not possible to directly convert amps into kVA without going through the accompanying calculations. Apparent power, denoted by "S" and measured by kVA, is equal to real power for a direct current (DC) circuit. However, for alternating current (AC) circuits, the real power and the apparent power differs by the ratio known as "power factor".

• A:

Converting kilowatts to amps first requires knowledge of the current type, whether it is DC, AC single phase or AC three phase, as each calculation differs. Additionally, the voltage in volts must also be known for all three calculations.

In general, watts are calculated by taking the current, in amps, and multiplying by the voltage. AC currents involve additional steps, which may include multiplying by a power factor (for single-phase currents) or multiplying by a power factor and a coefficient (for three-phase currents).

While both kVA and kW are units of measure, kVA is a kilo volt amperes and kW is a kilowatt. Both the kVA and the kW are units used to express power.
