What does one attojoule represent?

One attojoule is a very small unit of energy equal to 10^-18 joules, used for measuring energy levels at atomic and quantum scales.

How is horsepower (metric) hour defined?

One metric horsepower hour is the energy produced by sustaining one metric horsepower for one hour, equaling 2,647,795.5 joules.

Why convert attojoules to horsepower (metric) hours?

Converting attojoules to horsepower (metric) hours helps relate extremely small energy quantities found in physics or quantum devices to larger scale mechanical energy measurements useful in industry and history.
