Can someone explain units of electricity

how many wats in KV and how many KV in MegaVats it will be great if you post a complete chart as i know internet kilobyte to megabite

An AMPERE is the unit of measurement of electric current produced in a circuit by 1 volt acting through a resistance of 1 ohm.

An OHM is the unit of measurement of electrical resistance. It is the resistance of a circuit in which a potential difference of 1 volt produces a current of 1 ampere.

A WATT is the electrical unit of power: that is, the rate of energy transer equivalent to 1 ampere flowing under a pressure of 1 volt at unit power factor.

A WATT-HOUR is an electric energy unit of measure equal to 1 watt of power supplied to (or taken from) an electric circuit steadily for 1 hour.
