Kilowatt Hours (kWh)
No, kilowatt-hours are an exact measure of a quantity of energy. Energy is something that can be measured exactly and if you have an electricity supply at your house there is a meter that measures the kilowatt-hours you use. If you have a 40-watt light, it uses 40 watt-hours if it is on for an hour. If it is left on for 24 hours it uses 40 x 24 watt-hours, which is 0.96 kilowatt-hours, that might cost you 10-20 cents or pence.

It is not power which is measured in homes, but energy consumption. Electricity companies charge for energy consumption in kilowatt hours (kW.h). This is done using an energy meter (also known as a 'watt-hour meter' or 'kilowatt-hour meter'), which monitors the supply voltage, and the in-phase component of the load current.
watts or kilowatts are used to measure power, which is how quickly energy flows, and electrical energy is measured in kilowatt-hours. A kilowatt-hour is also known as a Unit of electrical energy, and it is the amount of energy used when a power of 1 kilowatt flows for 1 hour.
Electricity is measured in Kilowatt hours or for the symbols kWh
Actually, some characteristics of electricity are measured in voltage. Electrical quantity is measured in kilowatt hours, or kilojoules/hr. To answer your question more specifically, that particular unit of measurement (which corresponds, more or less, to electrical "pressure") is named in honor of Alexander Volta, a pioneer in the study of electricity.
