Horsepower Hour
A horsepower hour (hp*h) is a unit of energy representing the amount of energy equivalent to one horsepower of power sustained over one hour of time.
History/Origin
The horsepower hour originated from the traditional unit of horsepower used to quantify engine power, combined with the hour to measure energy consumption or production over time. It has been used primarily in engineering and energy industries to express energy usage or capacity.
Current Use
Today, the horsepower hour is rarely used in practical applications, having been largely replaced by the joule and other SI units. However, it may still be referenced in historical data, legacy systems, or specific industries dealing with older measurement standards within the energy and mechanical sectors.
Kilojoule
A kilojoule (kJ) is a unit of energy equal to 1,000 joules, used to quantify energy transfer or work done.
History/Origin
The kilojoule was introduced as part of the International System of Units (SI) to provide a convenient scale for measuring energy, especially in fields like nutrition and physics, replacing the joule for larger quantities.
Current Use
The kilojoule is widely used in nutrition to express food energy content, in physics and engineering to measure energy transfer, and in various scientific and industrial applications within the 'Energy' converter category.
