How to Convert Volt-Amperes to Horsepower
To convert volt-amperes to horsepower, multiply the power by the following conversion ratio: 0.001341 horsepower/volt-ampere.
Since one volt-ampere is equal to 0.001341 horsepower, you can use this simple formula to convert:
The power in horsepower is equal to the power in volt-amperes multiplied by 0.001341.
For example, here's how to convert 5 volt-amperes to horsepower using the formula above.
How Many Horsepower Are in a Volt-Ampere?
There are 0.001341 horsepower in a volt-ampere, which is why we use this value in the formula above.
Our volt-ampere to horsepower calculator automatically converts your power measurements with full decimal and scientific precision across US customary, imperial, and SI metric standards.
Volt-Amperes and horsepower are both units used to measure power. Keep reading to learn more about each unit.
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). [1]
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.
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). [2]
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.
When converting power between volt-amperes (VA) and horsepower (hp), keep full floating-point precision (1 VA = 0.001341 hp; 1 hp = 745.6998716 VA) during intermediate calculations and round only the final horsepower figure to match your instrument tolerance.
