马力

马力（英语：horsepower，hp），俗称匹，是一个古老的功率单位。今日除了航空、造船与汽车工业提及内燃机的功率、空调的制冷性能以外，在其他领域较为少用马力这个单位，而会使用标准的国际功率单位瓦特。

目前最常见的定义为：

这个单位概念是由蒸汽机改良者詹姆斯·瓦特命名，用以表示他的蒸汽机相对于马匹拉力的功率，定义为：一匹马在1分钟的时间，拖动半径为12英呎水车2.4圈，亦即(2.4*2π*12英呎)的距离

瓦特假设每匹马能拉动180磅，马力即可透过下式计算：功/时间=力*距离/时间=(180磅力)*(2.4*2π*12英呎)/1分钟=32572英呎·磅力/分钟。约等于33,000英呎‧磅力/分钟

There are many different standards and types of horsepower. 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. 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 definition of the unit varied between geographical regions. Most countries now use the SI unit watt for measurement of power. With the implementation of the EU Directive 80/181/EEC on January 1, 2010, the use of horsepower in the EU is permitted only as a supplementary unit. 近义、反义、联想词近义词 n. power unit 联想词 torque转矩，扭矩;engine引擎，发动机;acceleration加速;mpg每加仑行驶的英里数;supercharged超动力的;turbo涡轮增压机;RPM每分钟转数;dyno测力计;throttle节流阀;flywheel飞轮，惯性轮;octane辛烷;
