What Is a Horsepower?
A horsepower is a unit of power equal to 745.6998716 watts (W), the base unit for power. Imperial mechanical horsepower (550 ft·lbf/s ≈ 745.7 W). [1]
The horsepower is classified as a US customary and imperial unit of power. Horsepower can be abbreviated as hp; for example, 1 horsepower can be written as 1 hp.
When working with horsepower (hp) in formulas or technical specifications, always verify whether your target system uses SI metric, US customary, or British imperial standards.
In practice, horsepower (hp) are widely used across standard power applications within US customary and imperial workflows, engineering documentation, and technical data sheets.
What Is a Volt-Ampere?
A volt-ampere is a unit of power equal to 1 watts (W), the base unit for power. Apparent electrical power unit (equivalent to 1 W at unity power factor). [2]
The volt-ampere is classified as an International System of Units (SI) unit of power. Volt-Amperes can be abbreviated as VA; for example, 1 volt-ampere can be written as 1 VA.
When working with volt-amperes (VA) in formulas or technical specifications, always verify whether your target system uses SI metric, US customary, or British imperial standards.
In practice, volt-amperes (VA) are widely used across standard power applications within International System of Units (SI) workflows, engineering documentation, and technical data sheets.
When converting power between horsepower (hp) and volt-amperes (VA), keep full floating-point precision (1 hp = 745.6998716 VA; 1 VA = 0.001341 hp) during intermediate calculations and round only the final volt-ampere figure to match your instrument tolerance.
