Convert horsepower (metric) to attowatt
horsepower (metric)
Definition: The unit horsepower (symbol: hp) is a unit of measurement of power (the rate at which work is done). Mechanical horsepower, also known as imperial horsepower, is defined as approximately 745.7 watts (550 ft·lbf/s), while metric horsepower is approximately 735.5 watts (75 kgf·m/s). Boiler horsepower, albeit a less common measurement than either imperial or metric horsepower, is used for rating steam boilers, and is equivalent to 34.5 pounds of water evaporated per hour at 212 degrees Fahrenheit, or 9809.5 watts. In addition, when rating electric motors, one horsepower is equal to 746 watts.
History/origin: The term horsepower was adopted in the late 18th century by James Watt to compare the output of steam engines with the power of draft horses. Watt was not the first person to compare the output of horses to that of engines. As early as 1702, Thomas Savery referenced horses when describing the output of an engine. It is believed that Watt built on this idea and introduced the term horsepower, largely in an effort to market his steam engine. The term was later expanded to include other types of output power such as the imperial and metric horsepower measurements commonly used today.
attowatt
Definition: Attowatt is a measure of power, the rate at which work is done or energy is transferred. For conversion purposes, its value is 1.0e-18 times the reference unit, watt.
