What is a kilocalorie (th)?

A kilocalorie (thermochemical), symbol kcal (th), is a unit of energy equal to 1,000 thermochemical calories and defined as exactly 4,184 joules, often used for food energy content and thermal engineering.

How is horsepower hour defined?

A horsepower hour represents one horsepower of power delivered continuously for one hour, typically based on mechanical horsepower, approximately equal to 2.6845 million joules.

Why convert between kilocalorie (th) and horsepower hour?

Converting between these units helps relate thermal or food energy values to mechanical work output, useful in engineering fields for engine performance evaluation and energy management.
