Did you know? One horse does not have one horsepower. The number of ‘horsepower’ that comes advertised with your vehicle represents a basic unit of mechanical power that can be assessed in various ways. Some technical ones involve converting one horsepower to 735 watts, or in a physical conversion, 33,000 foot-pounds of torque per minute. By these measurements, a real horse averages only about 0.7 horsepower.
