Converting from one to other units of power

-

In physics, power is the rate at which energy is used, transferred or transformed. The SI unit of power is the Watt (symbol W, in honor of James Watt, who is the eighteenth-century developer of the steam engine). One Watt equals to 1 Joule per second (j/s). Also power can be measured in other units, such as horsepower (HP), metric horsepower, ergs per second (Erg/s) and foot-pound per minute. The term «power» is different from energy, because it is the value at which energy is changed and consumed.
