This is equivalent to 735.49875 W, or 98.6% of an imperial mechanical horsepower. British manufacturers often intermix metric horsepower and mechanical horsepower depending on the origin of the engine in question.ĭIN 66036 defines one metric horsepower as the power to raise a mass of 75 kilograms against the Earth's gravitational force over a distance of one metre in one second: 75 kg × 9.80665 m/s 2 × 1 m / 1 s = 75 kgf⋅m/s = 1 PS. The various units used to indicate this definition ( PS, KM, cv, hk, pk, ks and ch) all translate to horse power in English. Metric horsepower (PS, cv, hk, pk, ks, ch) One metric horsepower is needed to lift 75 kilograms by 1 metre in 1 second. In certain situations it is necessary to distinguish between the various definitions of horsepower and thus a suffix is added: hp(I) for mechanical (or imperial) horsepower, hp(M) for metric horsepower, hp(S) for boiler (or steam) horsepower and hp(E) for electrical horsepower.Īssuming the third CGPM (1901, CR 70) definition of standard gravity, g n = 9.80665 m/s 2, is used to define the pound-force as well as the kilogram force, and the international avoirdupois pound (1959), one mechanical horsepower is:ġ W ≡ 1 J/s = 1 N⋅m/s = 1 (kg⋅m/s 2)⋅(m/s) =flow rate (cubic feet / minute) × pressure (inches water column) / 6,356 = flow rate ( US gal/ min) × pressure (lbf/in 2) / 1714 = flow rate ( US gal/ min) × pressure ( lbf/in 2) × 7/12,000 Hp(M) – also PS, KM, cv, hk, pk, ks or ch The following definitions have been or are widely used: Mechanical horsepower Watt judged that the horse could pull with a force of 180 pounds-force (800 N). The wheel was 12 feet (3.7 m) in radius therefore, the horse travelled 2.4 × 2π × 12 feet in one minute. Watt determined that a horse could turn a mill wheel 144 times in an hour (or 2.4 times a minute). This royalty scheme did not work with customers who did not have existing steam engines but used horses instead. He had previously agreed to take royalties of one-third of the savings in coal from the older Newcomen steam engines. The idea was later used by James Watt to help market his improved steam engine. Then I say, such an engine may be made large enough to do the work required in employing eight, ten, fifteen, or twenty horses to be constantly maintained and kept for doing such a work. In 1702, Thomas Savery wrote in The Miner's Friend: So that an engine which will raise as much water as two horses, working together at one time in such a work, can do, and for which there must be constantly kept ten or twelve horses for doing the same. The development of the steam engine provided a reason to compare the output of horses with that of the engines that could replace them.

History A team of six horses mowing hay in Lancaster County, Pennsylvania With the implementation of the EU Directive 80/181/EEC on 1 January 2010, the use of horsepower in the EU is permitted only as a supplementary unit. Most countries now use the SI unit watt for measurement of power. The definition of the unit varied among geographical regions. It was later expanded to include the output power of other types of piston engines, as well as turbines, electric motors and other machinery. The term was adopted in the late 18th century by Scottish engineer James Watt to compare the output of steam engines with the power of draft horses. Two common definitions used today are the mechanical horsepower (or imperial horsepower), which is about 745.7 watts, and the metric horsepower, which is approximately 735.5 watts.

There are many different standards and types of horsepower. Horsepower ( hp) is a unit of measurement of power, or the rate at which work is done, usually in reference to the output of engines or motors. = 8.One mechanical horsepower lifts 550 pounds (250 kg) by 1 foot in 1 second. In relation to the base unit of => (newton meters), 1 Newton Meters (Nm) is equal to 1 newton-meters, while 1 Pound Foot (lb ft) = 1.35581795 newton-meters.
