 # calculating power how wind power works

• ### Physics for Kids: Power Ducksters

The standard unit for measuring power is the Watt. From the equation above we can see that power is Work ÷ Time. The unit for work is the joule (J), so a Watt is the same as a joule/second or J/s. Another common unit for power that is used for automobile engines and machines is horsepower. One horsepower is about equivalent to Watts.
