Calorie (It)
The calorie (cal) is a unit of energy traditionally used to quantify the amount of heat required to raise the temperature of one gram of water by one degree Celsius at standard atmospheric pressure.
History/Origin
The calorie was originally defined in the 19th century as a unit of heat energy in thermodynamics. It has historically been used in nutrition and physics, but has largely been replaced by the joule in scientific contexts. The 'small calorie' (cal) is distinct from the 'large calorie' (kcal), which is commonly used in food energy labeling.
Current Use
Today, the calorie is primarily used in nutrition to measure the energy content of foods and beverages, although the SI unit of energy, the joule, is increasingly preferred in scientific and technical fields.
Watt-Hour
A watt-hour (W·h) is a unit of energy equal to the amount of energy transferred or used when one watt of power is sustained for one hour.
History/Origin
The watt-hour was established as a practical unit of energy measurement with the adoption of the International System of Units (SI) and has been used in electrical and energy industries to quantify energy consumption and storage since the 20th century.
Current Use
Watt-hours are commonly used to measure electrical energy consumption in household appliances, batteries, and energy storage systems, providing a convenient unit for billing, capacity ratings, and energy management.
