Volt-Ampere to Metric Horsepower 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.

Metric horsepower (PS) is a unit of power equal to 75 kilogram-force meters per second, approximately 735.5 watts. It's the metric equivalent of horsepower, used primarily in European automotive and mechanical applications.

Metric horsepower was developed as a metric alternative to the imperial horsepower unit. It became standard in European automotive and mechanical industries, providing a power unit consistent with metric measurements while maintaining familiarity with the horsepower concept.

Metric horsepower is used in European automotive specifications, mechanical equipment ratings, and industrial machinery. It's standard for European car engine ratings, machinery specifications, and mechanical power systems in metric countries.
