What does 1 kilocalorie (IT) represent in joules?

1 kilocalorie (IT) equals 4,186.8 joules according to the international-table calorie definition.

What is a horsepower hour unit?

A horsepower hour is the energy produced by one mechanical horsepower of power sustained for one hour, approximately 2.6845 million joules.

Why use horsepower hour instead of joules or kilowatt-hours?

Horsepower hour is commonly used to measure mechanical work output or energy conversion related to legacy machinery or specific engineering contexts.
