Webb21 mars 2015 · Power is measured in watts. This can mean either the power that something produces as it works, or the power that is needed to drive something. A watt is not a very big unit of power. Powerful machines are therefore graded in kilowatts(KW) or megawatts(MW). A kilowatts is 1,000 watts and a megawatt is 1,000,000 watts. The dimension of power is energy divided by time. In the International System of Units (SI), the unit of power is the watt (W), which is equal to one joule per second. Other common and traditional measures are horsepower (hp), comparing to the power of a horse; one mechanical horsepower equals about 745.7 watts. Other units of power include ergs per second (erg/s), foot-pounds per minute, dBm, a logarithmic measure relative to a reference of 1 milliwatt, calories per hour, BTU pe…
