What is the reason for measuring the power of the engine with the "horse"?

Have you ever asked yourself why the motor's ability to measure the horse is measured, and what is the story of using this unit in the measurement.

Some say

It is a marketing trick invented by the Scottish engineer and inventor James Watt, who made major improvements to the steam engine invented by British Thomas Neukumin in 1712 and whose steam engines pumped water from mines all over the country.

In 1764, the Nukomin steam engine was signed by Watt for repair. He noted that he was no longer effective in performing his task and had to be improved to improve the quality of his performance. He designed a separate condensing chamber separate from the steam engine,

But persuading people to buy the new Watt device with the improvements he made was not easy. He needed a simple idea that he could understand to convince them to buy it

The idea came as he watched horses working in a mine and carrying coal on their backs. Watt noted that these horses were powerful and capable, and were able to transport 150 kilograms to 100 feet per minute. The power and power of the engine, which led Watt to connect the power of the steam engine and what can do in the minds of people with horsepower and thus linking the strength of these steam engines horsepower, where the strength of these engines force x of horses.

The marketing trick played a major role in the industrial revolution and thus became the unit of measurement of power of engines of all kinds and spread the term to a large extent to be adopted as a unit of measurement of the strength of the engine of the car as evidence of speed, strength and determination.


Thus, the car with the highest number of horsepower has greater capacity and torque than the rest of the cars

The higher the horsepower, the greater the momentum in the car, which is important and useful in racing cars, but the number of horses in the high standard cars means greater use of fuel.

Most people think there is a difference between horsepower and torque in the car and are seen as separate values ​​that do not relate to each other, but the force of the horse in the car is due to torque.

The performance of the vehicle is measured by its torque, which is measured dynamically and there is no machine to measure the number of horses that make up the force of the vehicle, as the number of horsepower is due to hit torque by the number of engine cycles per minute.
