Volt-Ampere to BTU per Hour Converter

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.

BTU per hour (BTU/h) is a unit of power representing the rate of energy transfer of one British Thermal Unit per hour. It's widely used in HVAC applications and provides a practical scale for heating and cooling system ratings.

BTU per hour became the standard power unit for HVAC systems and thermal equipment. It provided an appropriate scale for heating and cooling applications, becoming universally adopted in the HVAC industry and building energy systems.

BTU per hour is extensively used in HVAC systems, heating and cooling equipment ratings, building energy calculations, and thermal system specifications. It's standard for furnace ratings, air conditioner capacity, and building thermal load calculations.
