Etymology

The term 'horsepower' was first used by the Scottish inventor James Watt in the late 18th century as he sought to market his steam engines. Watt wanted to convey the power of his engines in a relatable way to potential customers, especially in comparison to the traditional power sources of the time, such as horses. He conducted experiments to determine how much work a horse could perform, estimating that one horse could turn a mill wheel of a specific size at a certain speed. From this, he calculated the value of one horsepower as a precise measure of power equivalent to the output of a horse. As machinery evolved, especially during the Industrial Revolution, horsepower became a standard measure for various types of engines, including automobiles. Today, it remains a popular and enduring term in the automotive industry and is used globally, despite the adoption of the metric system and the use of watts as the dominant unit of power in many regions.
