How to Convert Kilowatt to Horsepower (metric)Įxample: convert 15 kW to horsepower (metric):ġ5 kW = 15 × 1.3596216173 horsepower (metric) = 20.
Kilowatt to Horsepower (metric) Conversion Table Kilowatt The term was later expanded to include other types of output power such as the imperial and metric horsepower measurements commonly used today. How to Convert Kilowatt to MBH 1 kW 3.4121416331 MBH 1 MBH 0.2930710702 kW Example: convert 15 kW to MBH: 15 kW 15 × 3.4121416331 MBH 51. It is believed that Watt built on this idea and introduced the term horsepower, largely in an effort to market his steam engine. Over the course of an hour, one 9 watt LED uses 9 watt-hours. 009 kilowatts), a 5kW installation could power 555 LEDs indefinitely as long as perfect conditions remained 24/7 (5000 watts / 9 watts 555 LEDs). With LED light bulbs using about 9 watts (or. As early as 1702, Thomas Savery referenced horses when describing the output of an engine. A 5kW solar installation produces 5 kilowatts of electricity under perfect conditions. 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. You can also use our tool as an amp to hp calculator. In this case, a 1 hp motor to amps gives 4.505 A. We round the outcome to four significant figures. lbf/s), while metric horsepower is approximately 735.5 watts (75 kgf Make a fraction of these numbers and find the final horsepower to amps value, 746 / 165.6 4.505 A.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. Definition: A kilowatt (symbol: kw) is a unit of power in the International System of Units (SI).
