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energy in mechanical and engineering contexts, especially in the era of steam and early engines, but has largely been replaced by standard energy units like joules and kilowatt-hours.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 (Th)
The calorie (th) is a unit of energy used to quantify the amount of heat required to raise the temperature of one kilogram of water by one degree Celsius.
History/Origin
The calorie (th) was historically used in the context of thermochemistry and nutrition, originating from the calorie concept in the 19th century. It has largely been replaced by the joule in scientific contexts but remains in common use in some regions and fields.
Current Use
Today, the calorie (th) is primarily used in nutrition labeling and food energy measurements, especially in regions where the thermochemical calorie is still recognized, although the joule is the SI standard.
