Btu (th), or thermochemical British thermal unit, is a unit of energy defined as the heat required to raise one pound of water by one degree Fahrenheit based on a thermochemical calorie basis.

What is kilocalorie (th)?

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

Why convert Btu (th) to kcal (th)?

Converting these units helps express energy content appropriately across different applications like fuel ratings, nutrition labeling, and chemical engineering studies.
