What does electric horsepower represent?

Electric horsepower is a power unit used in rating electric motors, defined as exactly 746 watts, representing the power produced by an electric machine equivalent to one mechanical horsepower.

What is a megajoule per second (MJ/s)?

Megajoule per second is a power unit representing one million joules of energy transferred or converted each second, equivalent to one megawatt, often used for large-scale power generation and thermal processes.

Why convert horsepower (electric) to megajoule/second?

Converting allows comparison between smaller electric motor ratings and large-scale energy outputs such as power plants or industrial heat transfer, enabling standardization and better energy management.
