Horsepower (Metric) Hour
A unit of energy representing the amount of work done by one horsepower over one hour, equivalent to 745.7 joules.
History/Origin
The horsepower hour was historically used to quantify energy in mechanical and engineering contexts, especially in the era of steam and early engines, but has largely been replaced by standard energy units like joules and kilowatt-hours.
Current Use
It is rarely used in modern practice, but may still appear in legacy systems or specific industrial applications to measure energy output or consumption related to horsepower-rated equipment.
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 It has historically been used in nutrition and physics, but has largely been replaced by the joule in scientific contexts.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.
