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. WebbThe standard electrical units are defined in a specific order. The ampere is defined first. It is an SI base unit, the only electrical unit derived from the outcome of an experiment. Next up after the ampere comes the coulomb and charge on an electron. Then we derive the rest of our favorites, the watt, the volt, and the ohm.
