The Ford Mustang GT packs a lot of power and has a 060 time of 4.1 seconds. It is equipped with its famous 5.0-liter V8 engine that produces 480 horsepower and 420 pounds of torque. The most common Ford Mustang GT has a top speed of 163 mpg. In the United States, the power output is stated in horsepower, which for this purpose is defined as precisely 746 W. One metric horsepower is the power to raise a mass of 75 kilograms against the Earth's gravitational force over a distance of one meter in one second.ħ5 kg × 9,80665 m / s2 × 1 m / 1 s = 75 kgf ⋅m / s = 1 PSĮlectrical horsepower: Nameplates on electrical motors show their power output, not the power input (the power delivered at the shaft, not the energy consumed to drive the motor). The various units used to indicate this definition (PS, KM, cv, HK, pk, ks, and ch) translate to horsepower in English. Metric horsepower (PS, cv, HK, pk, ks, ch) Mechanical horsepower: definition of standard gravity, gn = 9.80665 m / s2, is used to define the pound-force as well as the kilogram-force, and the international avoirdupois pound, one mechanical horsepower is: 745.699W Below we will list and explain most of them. We have several types and definitions of horsepower. Heat is now known to be equivalent to energy. It is defined as the amount of heat required to raise one pound of water by one degree Fahrenheit at a constant pressure of 1 atmospheric unit. The British Thermal Unit (BTU) is a unit of heat. H = T x rpm / 5252, where T is pound-feet, rpm is how fast the engine is spinning, and 5252 is a constant that makes the units jibe. Horsepower is equal to the torque multiplied by rpm. In other words, power is the rate of doing work at a given time. Torque is the capacity of work, while power is how fast some work can be done in a given time. Power- is a physical quantity that describes the speed of mechanical work, determined by the ratio of work W and the time spent t. Torque gives the body angular acceleration. Torque- is a physical vector quantity that plays a similar role in body rotation as a force in body translation. Work- is a physical quantity that describes the action of a force. Energy is found in nature in various forms, converted from one type of energy to another. Air and fuel ignite in the combustion chamber and move the crankshaft, transmission, and drive axles to make a turn.Įnergy- is the ability of a body to do some work. Torque and power are what the engine produces when started. We mention horsepower and torque all the time to explain what it means. Watts = 111.854 W or 111.85 kW Horsepower vs torque Once we know the value of one horsepower, you can convert horsepower to watts using the following formula:įor example, we will convert the horsepower of the average car to watts (150hp). Using Watt's Law, it's possible to express the power in watts using current and voltage. Watt's Law states the relationship between power, current, and voltage. Watts can be abbreviated as W for example, 1 watt can be written as 1 W. ![]() Watt is the SI-derived unit for power in the metric system. It was named after the 18th-century Scottish scientist James Watt. It is used to quantify the rate of energy transfer. Watt is a unit of power in the International System of Units (SI), defined as a unit derivative of 1kg*m^2*s^ -3 which is equivalent to 1 joule per second. We can turn this into kilowatts that are more familiar to us in cars.ġ8641.75 W = 18.64 kW Horsepower to watts conversionīefore we show you how to turn horsepower into a watt, let’s briefly say what a watt is. One mechanical or hydraulic horsepower is equal to 745.67 Wattsįormula for converting horsepower to watts: Multiply the torque value by the speed values of the engine. We use a simple formula to calculate horsepower. It measures how much energy we need to lift 227 kilograms (550 lbs) to a height of 0.30 meters (one foot) in a time of one second or the power with which it will move 14.968kg (33.000lbs) 0.30 meters (one foot) in time of one minute. In short, horsepower is compared to the power produced by the engine. Eventually, this began to be applied with other machinery such as turbines, electric motors. This 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. The two most commonly used are mechanical horsepower (imperial horsepower), approximately 745.7 watts, and the metric horsepower, 735.5 watts. Otherwise, it is a reference to how much energy comes out of the engine. Horsepower (HP) is a unit for measuring power or the rate at which work is done.
