What does one watt-second represent?

A watt-second is the energy transferred by one watt of power sustained for one second, dimensionally equal to one joule.

Why convert watt-seconds to metric horsepower hours?

Converting allows comparison between electrical energy measurements and mechanical energy output, especially useful in engine testing and efficiency calculations.

Are there any challenges when converting these units?

Yes, because watt-seconds measure small energy quantities and horsepower hours measure much larger ones, conversions often result in very small decimal numbers requiring precise handling.
