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.
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.
