Horsepower (metric) to Watt Conversion Table Horsepower (metric) The watt as a unit of power should not be confused with its energy counterpart, the watt-hour (and all its multiples/submultiples). The absolute watt was adopted as the SI unit of power in 1960.Ĭurrent use: As the SI derived unit of power, the watt in all its multiples and submultiples is used in many applications worldwide from radio transmission to use in the electric power industry. 1 absolute watt is equal to 1.00019 international watts. When considering human-powered equipment, a healthy human can produce about 1.2 hp (0.89 kW) briefly (see orders of magnitude) and sustain about 0.1 hp (0.075 kW) indefinitely trained athletes can manage up to about 2.5 hp (1.9 kW) briefly and 0.35 hp (0.26 kW) for a period of several hours. ![]() These were used until 1948 when the General Conference on Weights and Measures re-defined the watt to absolute units, using only mass, time, and length. In 1908, the "international" definitions were defined, with Siemens' definition being adopted as the international watt. It was first proposed in 1882 by William Siemens who defined it as "the power conveyed by a current of an Ampere through the difference of potential of a Volt." This was the definition used at the time within the existing system of units. History/origin: The watt is named after James Watt, a Scottish inventor. It is defined as 1 joule per second and is used to quantify the rate of energy transfer. ![]() Wattĭefinition: A watt (Symbol: W) is the SI (International System of Units) derived unit of power. How many horsepower are in a watt 1 watt 0.00134103 horsepower 2 watts 0.00268206 horsepower 3 watts 0.00402309 horsepower 4 watts 0.00536412. 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. The condenser compresses the refrigerant and circulates it through a series of coils. The Power of an Air Conditioner An air conditioner consists of a condenser, a system of coils and a refrigerant. It is the power needed to do one joule of work per second. Mechanical horsepower is commonly used to measure the maximum power of a cars engine in the United States or the UK. Watt was not the first person to compare the output of horses to that of engines. Because 1 kW 1,000 watts, 1 hp 0.7457 kW. What is 0.03 horsepower in watts 0.03 hp (I) to W conversion. 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. Among the many different measurements of horsepower Imperial Mechanical Horsepower is most commonly used in. 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. Approximately 745.69987158227022 Watts (SI). 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 One watt is equal to 0.0013596216 hp (metric).Definition: The unit horsepower (symbol: hp) is a unit of measurement of power (the rate at which work is done). Watt indicates the radiation of energy per second. One joule per second is equivalent to watt. Watt (W) is a unit of measuring unit of power in the international standard system unit. One 1 horsepower (metric) is equal to 735.49875 W. imperial horsepower is 745.7 watts, and metric horsepower is 735.5 watts. ![]() There are two kinds of standard horsepower imperial horsepower and metric horsepower. Horsepower (hp) is a measuring unit of power. It is a free online horsepower to watts (hp to w) power converter. imperial horsepower is 745.7 watts, and metric horsepower is 735.5 watts. second 1 000 watts 1.341 4 horsepower 56.91 Btu per minute 737.8 foot - pounds per second 1 watt - hour per second 3 600 watts 3.6 kilowatts. ![]()
