How to Convert Kilowatt to Horsepower (metric)Įxample: convert 15 kW to horsepower (metric):ġ5 kW = 15 × 1.3596216173 horsepower (metric) = 20. Watt Missed the True ‘Horsepower’ In rating his steam engines at 10 horsepower, Watt had made a slight error. Instead, 1000 watts (1.0 kilowatt) is equal to 1.3 horsepower, and a 60-watt light bulb consumes 0.08 horsepower, or 1.0 horsepower equals 746 watts. Kilowatt to Horsepower (metric) Conversion Table Kilowatt Ironically, however, one watt does not equal one horsepower.
The term was later expanded to include other types of output power such as the imperial and metric horsepower measurements commonly used today. It is believed that Watt built on this idea and introduced the term horsepower, largely in an effort to market his steam engine. As early as 1702, Thomas Savery referenced horses when describing the output of an engine.
Watt was not the first person to compare the output of horses to that of engines. History/origin: The term horsepower was adopted in the late 18 th century by James Watt to compare the output of steam engines with the power of draft horses. In addition, when rating electric motors, one horsepower is equal to 746 watts. 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. lbf/s), while metric horsepower is approximately 735.5 watts (75 kgf.Mechanical horsepower, also known as imperial horsepower, is defined as approximately 745.7 watts (550 ft Horsepower (metric)ĭefinition: The unit horsepower (symbol: hp) is a unit of measurement of power (the rate at which work is done). Megawatt or gigawatt hours may be used in larger buildings or for industrial applications. Electricity used by a home is typically measured in kilowatt hours, or kWh, meaning 1000 watts being applied over a period of one hour. He defined the unit within the system of units being used at the time, and his definition was adopted in 1908.Ĭurrent use: Kilowatts are used worldwide, typically to express the output power of engines and the power of electric motors, tools, machines, and heaters. This was first proposed in 1882 by Sir Charles William Siemens, an engineer and entrepreneur, who suggested the use of Watt's name as a unit of power. History/origin: The base unit of the kilowatt is the watt, which was named after a Scottish inventor named James Watt. As is consistent with SI units, the prefix kilo- means that a kilowatt equals one thousand watts or one thousand joules per second. The base unit of the kilowatt is the watt, which was named after Scottish inventor James Watt.
