a unit of power representing the power exerted by a horse in pulling. The horsepower was defined by James Watt (1736-1819), the inventor of the steam engine, who determined after careful measurements that a horse is typically capable of a power rate of 550 foot-pounds per second. This means that a horse, harnessed to an appropriate machine, can lift 550 pounds at the rate of 1 foot per second. Today the SI unit of power is named for Watt, and one horsepower is equal to approximately 745.6999 watts. (Slightly different values have been used in certain industries.) Outside the U.S., the English word "horsepower" is often used to mean the metric horsepower, a slightly smaller unit.

One horsepower is the amount of work required to move 550 lbs one foot in one second

The unit of work assigned to many mechanical devices including the internal combustion engine. Horsepower is defined as the ability to perform 33,000 foot pounds of work in one minute. Note that this expression contains the work definition of force acting through a distance expressed in foot pounds, and also the power definition (has the element of speed or time associated with it) since the element of time is considered.

Torque measures how much work (an engine) can do, power is the rate-based measurement of how fast the work is being done. Starting with the static force applied at the end of a torque arm (torque), then multiplying this force by the swept distance through which the same force would rotate one full revolution finds the power per revolution: Power Per Revolution = Force or Weight x Swept Distance. James Watt (1736-1819) established the current value for one horsepower: 33,000 pound-feet per minute or 550 pound-feet per second. So horsepower is currently calculated as: Horsepower = Power Per Revolution/33,000, which is the same as Horsepower = (Torque x 2 x Pi x RPM)/33,000, or simply: Horsepower = (Torque x RPM)/5,252. The horsepower being calculated by these equations is just one of several ways to rate engine power output. Various additional methods for calculating or measuring engine horsepower are commonly used (to derive friction horsepower, indicated horsepower, etc.), and each technique provides additional information about the engine under test.

An index of the amount of work a machine or motor can perform. One horsepower is equal to 746 watts. Since power is equal to torque multiplied by speed, horsepower is a measure of a motor's torque and speed capability; e.g., a 1 HP motor will produce 36 lb-in. at 1,750 rpm. Formula: HP = Torque (lb-in.) x Speed (RPM)/63,025 or HP = Torque (lb-ft.) x Speed (RPM)/5,252 or HP = Volts x Amps x Efficiency/746

Metric usage is to express "power" as kilowatts, or kW, rather than the old fashioned hp or bhp (brake horsepower). The more kW, the more power. Also important to the engine's ability to perform is the power:weight ratio. Some engines are best at moderate engine speeds (rpm) while others have to be revved much higher to produce their maximum horsepower. More relevant for day to day driving is torque, or pulling power, and how the car responds at ordinary engine revs (see Torque).

The more horsepower a lawnmower's engine has, the easier it will be for the mower to cut the grass. Of course this is not a perfect correlation. A 4hp mower with a razor sharp blade will cut grass better than a 5hp mower with a dull blade. More power enables the mower to cut more evenly and cleanly through high or wet grass. If you are using a riding mower to tow, it will be able to tow larger loads if it has more horsepower.

The power produced by an engine. Net horsepower or bhp (brake horsepower) and Kw (kilowatts) are the standard units. Higher horsepower increases vehicle top speed. Equal displacement (size) engines that rev higher often produce more power than lower revving engines, because more air and fuel is burned in a given time. A typical 3.0L 24V V-6 produces 190 bhp @ 6400 RPM. A lower revving 3.0L 12V V-6 produces 160 bhp @ 5000 RPM. The 24-valve V-6 makes 190 bhp because it can rev higher (and breathe better) than the similar 12-valve V-6.
