A therm is an imperial unit of heat energy equal to 100,000 BTU or approximately 105,506,000 joules. It is used primarily for natural gas billing.

History

The therm was defined by the UK Gas Act of 1920 for standardizing natural gas billing. It provided a convenient large-scale unit for measuring gas consumption across households and businesses.

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.
