Watt-hours (Wh)
Definition
A watt-hour (Wh) is a unit of energy equal to the work done by one watt of power sustained for one hour. It equals 3,600 joules.
History
The watt-hour emerged with the development of electrical power systems in the late 19th century. It provided a practical way to measure and bill for electrical energy consumption.
Current use
Watt-hours are used for small battery capacities (e.g., phone batteries, portable electronics) and as a base unit for kilowatt-hours used in household electricity metering.
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.
