Convert metric horsepower hour to j
Metric Horsepower-Hour
A metric horsepower-hour is a unit of energy equal to the work done by one metric horsepower (735.499 W) sustained for one hour, equivalent to approximately 2,647,795.5 joules (2.648 MJ). It is the metric counterpart of the mechanical horsepower-hour and was used in European engineering and automotive contexts. The unit is largely obsolete, having been replaced by the kilowatt-hour in most applications.
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).
