Hectowatt to Kilovolt-Ampere Converter

A hectowatt (hW) is a unit of power equal to one hundred watts (10² W). It represents moderate power levels found in small appliances, lighting systems, and medium-scale electrical equipment.

The hectowatt developed as part of the metric system's decimal structure, providing an intermediate unit between kilowatts and watts. It became useful for describing power consumption of small appliances and lighting systems where watts would be large numbers.

Hectowatts are used for small appliance ratings, lighting system specifications, and medium-scale electrical equipment. They're found in specifications for small motors, lighting installations, and electrical systems requiring moderate power levels.

Kilovolt-ampere (kVA) is a unit of apparent power equal to one thousand volt-amperes. It's widely used for rating large AC electrical equipment, transformers, and electrical systems where apparent power is the primary concern.

Kilovolt-ampere became standard with the growth of large AC electrical systems and power distribution. It provided an appropriate scale for rating transformers, generators, and large electrical equipment where apparent power capacity was the critical specification.

Kilovolt-amperes are extensively used for transformer ratings, generator specifications, large UPS systems, and electrical distribution equipment. They're standard for power system design, electrical equipment ratings, and AC power capacity specifications.
