What is Energy?
Energy is the capacity of a physical system to do work or produce heat. The SI unit is the joule (J), defined as the work done when a force of one newton is applied over one metre (1 J = 1 N·m = 1 kg·m²/s²). Other important units include the kilowatt-hour (kWh)—used on electricity bills (1 kWh = 3.6 MJ)—the calorie (cal)—used in nutrition (1 food Calorie = 1 kcal = 4,184 J)—and the electronvolt (eV), used in atomic and particle physics (1 eV = 1.602 × 10⁻¹⁹ J).
What is Kilojoule?
The kilojoule (kJ) is an SI-derived unit of energy equal to 1,000 joules (J). It is widely used to measure mechanical work, heat, electrical energy, chemical energy, and food energy. The kilojouleis commonly used in science, engineering, and nutrition because it expresses larger energy values more conveniently than the joule.
What is Horsepower-hour?
A horsepower-hour (symbol: hp·h) is a unit of energy equal to the amount of energy delivered by a power output of one horsepower maintained for one hour. In common usage based on the mechanical horsepower, 1 horsepower-hour is approximately 2.6845 megajoules (MJ). Horsepower-hours are used in mechanical engineering, engine performance analysis, industrial machinery, and historical equipment specifications to express the total energy produced or consumed over time.
The exact energy represented by a horsepower-hour depends on the definition of horsepower being used, such as mechanical horsepower, metric horsepower, or electrical horsepower. Unless otherwise specified, conversion tools commonly use the standard mechanical horsepower definition. When comparing technical documents, it is important to verify which horsepower standard applies.
Horsepower-hours are occasionally used to estimate the energy output of engines, turbines, pumps, compressors, and other mechanical equipment. Although the International System of Units (SI) uses the joule as the standard unit of energy, the horsepower-hour remains useful in industries and regions where horsepower is still commonly used to describe power ratings.
