Kilowatt to Volt-Ampere Converter

A kilowatt (kW) is a unit of power equal to one thousand watts (10³ W). It's one of the most commonly used power units, representing the power consumption of household appliances and small to medium electrical equipment.

The kilowatt became widely recognized with the expansion of electrical power to homes and businesses in the early 20th century. It provided a practical scale for household electricity consumption and became the standard unit for electrical billing and appliance ratings.

Kilowatts are universally used for household appliance ratings, small motor specifications, residential solar installations, and electricity billing. They're standard for home electrical consumption, appliance energy labels, and small-scale power systems.

Volt-ampere (VA) is a unit of apparent power in AC electrical systems, representing the product of voltage and current. It differs from watts (real power) in AC systems where voltage and current may not be in phase.

Volt-ampere became important with the development of AC electrical systems, where the distinction between apparent power and real power became crucial. It provided a way to specify the total power capacity of AC electrical equipment regardless of power factor.

Volt-amperes are used for AC electrical equipment ratings, transformer specifications, and electrical system design. They're standard for UPS ratings, transformer capacity, and AC electrical equipment where apparent power is more relevant than real power.
