Understanding the Units

What is a Megacalorie?

A kilocalorie (kcal) equals 1,000 small calories, or 4,184 joules. In nutrition, the food "Calorie" (capital C) refers to the kilocalorie.

Common contexts: nutrition (US), metabolism, food labeling.

What is a Joule?

The joule is the SI derived unit of energy, equal to the work done by a force of one newton acting through a distance of one meter (1 J = 1 N·m = 1 W·s).

Named after James Prescott Joule (1818–1889), the English physicist who demonstrated the mechanical equivalent of heat.

Common contexts: physics, chemistry, engineering.
