Horsepower to Decawatt Converter

Horsepower (hp) is a unit of power originally defined as the power needed to lift 550 pounds one foot in one second, approximately equal to 746 watts. It was created to compare the output of steam engines with the power of draft horses.

Horsepower was defined by James Watt around 1782 to market his steam engines by comparing their output to the familiar power of horses. It became the standard unit for mechanical power in English-speaking countries and remains widely used despite the adoption of SI units.

Horsepower is extensively used in automotive engines, mechanical equipment, and motor specifications. It's standard for car engine ratings, industrial machinery, pumps, and mechanical power transmission systems, particularly in the United States.

A decawatt (daW) is a unit of power equal to ten watts (10¹ W). It represents small power levels typically found in low-power appliances, electronic devices, and small electrical systems.

The decawatt developed as part of the metric system's decimal structure, providing a convenient intermediate unit between watts and smaller power measurements. It became useful for describing power consumption of small electronic devices and low-power systems.

Decawatts are used for low-power appliance ratings, electronic device specifications, and small electrical systems. They're found in specifications for small electronic devices, LED lighting, and low-power electrical equipment.
