What Is This Tool?
This tool converts power units from horsepower (hp, hp (UK)), a mechanical power measure commonly used in engines and motors, to kilovolt ampere (kV*A), an electrical power unit representing apparent power in AC systems.
How to Use This Tool?
-
Enter the horsepower value you want to convert.
-
Select the unit as horsepower (hp, hp (UK)) for the input.
-
Choose kilovolt ampere (kV*A) as the output unit.
-
Click convert to see the equivalent power measurement in kilovolt amperes.

Review the result and use it for your power system or engineering calculations.
Key Features
-
Converts mechanical horsepower ratings to electrical apparent power in kilovolt amperes.
-
Uses established conversion based on horsepower defined as 550 foot-pounds per second (approx. 745.7 watts).
-
Provides clear conversion formulas and practical examples.
-
Supports common engineering and industrial power unit needs.
-
Browser-based with an intuitive interface for quick calculations.
Examples
-
5 horsepower converts to approximately 3.7285 kV*A (5 × 0.7456998716).
-
10 horsepower equals about 7.4570 kV*A (10 × 0.7456998716).
Common Use Cases
-
Translating engine power ratings into electrical apparent power values for comparison.
-
Specifying power ratings for motors, pumps, and small engine equipment.
-
Designing electrical systems that interface with mechanical power sources.
-
Planning transformer and generator capacities based on mechanical power inputs.
-
Assessing total electrical load in industrial and automotive applications.
Tips & Best Practices
-
Always verify the variant of horsepower being used (mechanical vs. metric) for accurate context.
-
Understand that kilovolt ampere measures apparent power and may not reflect actual active power.
-
Use this conversion as an approximate guide when comparing mechanical and electrical power ratings.
-
Consider power factor and real power when applying these conversions to electrical system designs.
Limitations
-
Conversion assumes mechanical horsepower defined as about 745.7 watts, but other variants exist.
-
Kilovolt ampere measures apparent power; it does not directly account for power factor or real power.
-
The conversion provides approximate equivalencies, not exact active power values.
Frequently Asked Questions
-
What is horsepower in this conversion?
-
Horsepower here refers to the mechanical horsepower defined as 550 foot-pounds per second, roughly 745.7 watts.
-
What does kilovolt ampere represent?
-
Kilovolt ampere (kV*A) is a unit of apparent power in AC electrical systems, measuring the product of RMS voltage and current without considering phase angle.
-
Why convert horsepower to kilovolt ampere?
-
This conversion helps translate mechanical power ratings into electrical apparent power values for comparison and system specification.
Key Terminology
-
Horsepower [hp, hp (UK)]
-
A non-SI unit of mechanical power equal to 550 foot-pounds per second or about 745.7 watts, commonly used for engine ratings.
-
Kilovolt ampere [kV*A]
-
A unit of apparent power in AC electrical systems equal to 1,000 volt-amperes, representing RMS voltage multiplied by RMS current.
-
Apparent Power
-
Power measured as the product of RMS voltage and RMS current in AC circuits, without accounting for phase angle or power factor.
