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energy in mechanical and engineering contexts, especially in the era of steam and early engines, but has largely been replaced by standard energy units like joules and kilowatt-hours.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.
Megajoule
A megajoule (MJ) is a unit of energy equal to one million joules.
History/Origin
The megajoule was introduced as part of the metric system to measure large amounts of energy, especially in scientific and engineering contexts, aligning with the SI units established in the 20th century.
Current Use
The megajoule is used in fields such as physics, engineering, and energy industries to quantify large energy quantities, including in energy production, consumption, and scientific research.
