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.
Microjoule
A microjoule (µJ) is a unit of energy equal to one millionth of a joule, used to measure small amounts of energy.
History/Origin
The microjoule was introduced as part of the metric system to facilitate the measurement of very small energy quantities, especially in scientific and engineering contexts, with the adoption of the International System of Units (SI).
Current Use
Microjoules are commonly used in fields such as electronics, physics, and biology to quantify small energy transfers, signals, or reactions, often in research and technical applications.
