The Conversion Formula

To convert watts to horsepower, multiply the value by the conversion factor: 1 W = 0.00134102 hp. For a worked example, suppose you need to convert 25 W to horsepower: 25 × 0.00134102 = 0.0335255 hp. To convert in the opposite direction, divide by 0.00134102, or equivalently multiply by 745.7.

About watts

The Watt (W) is the SI unit of power, equivalent to one Joule per second. It is named after James Watt, the inventor of the modern steam engine. It is the standard for measuring electrical power worldwide, from LED bulbs to supercomputers. watts are commonly used in Light bulbs, Electronics, Speakers, and Scientific data, Cycling (power output).

A typical LED bulb uses about 9 Watts.

About horsepower

Horsepower (hp) was coined by James Watt to market his steam engines to millers who used horses. He calculated that a horse could do 33,000 foot-pounds of work per minute. It remains the dominant unit for cars, boats, and lawnmowers in the US, despite being an archaic estimation of an animal's strength. horsepower are commonly used in Car engines, Lawnmowers, Boat motors, and Industrial pumps (US), Marketing materials.

A Toyota Camry has about 200 horsepower.

When Would You Convert watts to horsepower?

Converting between watts and horsepower is one of the most common power conversions. You might need this conversion when working with international specifications, following instructions written for a different measurement system, or comparing values across different standards. Having the conversion factor (1 W = 0.00134102 hp) memorized or bookmarked can save time in professional and everyday contexts alike.
