What does one hectojoule per second represent?

One hectojoule per second equals 100 joules per second or 100 watts, representing the rate of energy transfer.

Why use horsepower instead of watts?

Horsepower is traditionally used in mechanical and automotive contexts, especially in countries using imperial units, to rate engine and motor power.

Is the conversion from hJ/s to horsepower exact?

No, horsepower is an approximate measure, so conversions can introduce rounding errors and differ from precise watt measurements.
