What is one megajoule (MJ)?

One megajoule is an SI derived unit of energy equal to one million joules, used to measure transferred or stored energy such as work, heat, or chemical energy.

How much energy does one metric horsepower hour represent?

One metric horsepower hour equals the energy produced by sustaining one metric horsepower for one hour, which is approximately 2,647,795.5 joules or about 0.73549875 kilowatt-hours.

Why convert from megajoules to metric horsepower hours?

Converting from megajoules to metric horsepower hours helps translate large-scale or engine-related energy measurements into mechanical output terms for use in performance analysis and fuel efficiency calculations.
