What does 1 kilojoule represent?

One kilojoule (kJ) is an SI-derived unit of energy equal to 1,000 joules and is used to quantify work, heat, or energy transfer.

How is a horsepower hour defined?

A horsepower hour (hp*h) denotes the energy delivered by one mechanical horsepower continuously for one hour, approximately equal to 2.6845 million joules.

Why convert kilojoules to horsepower hours?

Converting kilojoules to horsepower hours helps evaluate mechanical energy equivalents of thermal or electrical energy, useful in engineering, machinery design, and legacy equipment analysis.
