What does one metric horsepower hour represent?

It represents the energy delivered by sustaining one metric horsepower for one hour, equaling 2,647,795.5 joules.

Is newton meter used only for torque?

No, the newton meter also expresses work or energy transferred, where 1 N·m equals 1 joule, though torque and energy are conceptually different.

Why convert horsepower (metric) hour to newton meters?

Conversion helps relate engine energy output to fundamental SI units used in physics and engineering for calculations and efficiency analysis.
