Convert horsepower hour to j
Horsepower Hour
The horsepower-hour (hp·h) is a unit of energy equivalent to the work done by a one-horsepower engine operating continuously for one hour, equal to approximately 2.685 × 106 joules (2.685 MJ). It was historically used to measure the output of steam engines and mechanical equipment. Today it is occasionally found in older engineering literature and in contexts comparing engine efficiencies and fuel consumption.
Joule
The joule (/dʒaʊ,dʒuːljawl, jool; symbol: J) is a derived unit of energy in the International System of Units. It is equal to the energy transferred to (or work done on) an object when a force of one newton acts on that object in the direction of the force's motion through a distance of one metre (1 newton metre or N⋅m). It is also the energy dissipated as heat when an electric current of one ampere passes through a resistance of one ohm for one second. It is named after the English physicist James Prescott Joule (1818–1889).
