No. 4. James Watt and Horsepower

Bild   •   Aug 13, 2019 08:24 CEST

To illustrate the enormous power of his steam engine, James Watt invented a new unit of measurement: The horsepower. He measured how much a group of ponies could lift and compared it to the power of his steam engine. One horsepower corresponded to the power of a strong horse that could pull the weight of 550 pounds over a distance of one foot in one second. Strategically, it was a very important and smart move by James Watt, as it enabled him to market his steam engine better. The horsepower is still used today - especially in the automotive industry.
