Horsepower (Metric)
The metric horsepower (hp) is a unit of power defined as exactly 735.5 watts, used to measure the power output of engines and motors.
History/Origin
The metric horsepower was introduced in the late 19th century as a standardized unit to quantify engine power, primarily in Europe, replacing traditional units like the imperial horsepower. It was adopted for consistency in engineering and automotive industries.
Current Use
Today, the metric horsepower is used mainly in automotive, engineering, and industrial contexts to specify engine power, especially in regions that utilize the metric system. It is also used in some countries for rating motor and engine capacities.
Kilojoule/hour
A kilojoule per hour (kJ/h) is a unit of power representing the amount of energy in kilojoules transferred or converted per hour.
History/Origin
The kilojoule per hour has been used as a measure of power in contexts where energy transfer rates are expressed over time, particularly in engineering and scientific applications, though it is less common than standard SI units like watts.
Current Use
kJ/h is used in specific fields such as thermodynamics and energy management to quantify energy transfer rates, especially in systems where energy is measured in kilojoules and the rate is expressed per hour, though it is often converted to watts for standardization.
