Volt-Ampere to BTU per Second 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 second (BTU/s) is a unit of power representing the rate of energy transfer of one British Thermal Unit per second. It's used in thermal engineering and HVAC applications, particularly in imperial unit systems.

BTU per second developed with the British Thermal Unit system and became important in thermal engineering and HVAC applications. It provided a power unit consistent with BTU energy measurements, particularly useful in heating and cooling system design.

BTU per second is used in HVAC engineering, thermal system design, and heating/cooling applications. It's standard in imperial unit thermal calculations, boiler specifications, and air conditioning system ratings.
