What does calorie (th)/hour measure?

It measures the rate of heat transfer or thermal power based on the thermochemical calorie delivered per hour.

Where is metric horsepower commonly used?

It is used to rate engine power in cars and motorcycles, particularly in European and Asian markets, and for specifying mechanical power in industrial equipment.

Why might the converted values be very small?

Because calorie (th)/hour measures very small thermal power compared to the larger scale mechanical power represented by metric horsepower.
