Kilocalories (kcal)

Definition

A kilocalorie (kcal), also known as a food calorie or large calorie, equals 1,000 small calories or approximately 4,184 joules. It is the standard unit for measuring dietary energy.

History

The kilocalorie became the standard unit for food energy labeling in the United States and many other countries during the 20th century. Nutritionist Wilbur Olin Atwater pioneered its use in dietary science.

Current use

Kilocalories are the primary unit for food energy on nutrition labels in the US, Canada, and much of Asia. They are also used in exercise science, dietetics, and metabolic rate calculations.

Ergs

Definition

An erg is a CGS (centimeter-gram-second) unit of energy equal to 10⁻⁷ joules. It represents the work done by a force of one dyne over a distance of one centimeter.

History

The erg was the standard energy unit in the CGS system, widely used in physics before the SI system gained dominance. It was introduced in the mid-19th century alongside other CGS mechanical units.

Current use

Ergs are still used in astrophysics and some branches of physics, particularly for describing stellar energy output, supernova energies, and spectroscopic measurements in legacy literature.
