watts (W)

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.

A typical LED bulb uses about 9 Watts.

Commonly used in: Light bulbs, Electronics, Speakers, Scientific data, Cycling (power output).

horsepower (hp)

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.
