A device used to indicate instantaneous power usage.
Square meter is area and Kilowatt is energy. There is no equivalent.
The meter on the side of your house is a watt meter. You are charged for the electricity that you use in kilowatt/hours. See related links below
The watt (or kilowatt) is a unit of power (energy/time). Kilowatt per unit area, for example, kilowatt per square meter, doesn't have a special unit name, but the thing measured is called intensity.
'Balanced loads' apply to three-phase a.c. loads. A three-phase kilowatt hour meter will measure both balanced and unbalanced loads, when correctly connected.
An electricity meter is an energy meter, and measures the amount of energy, expressed in kilowatt hours, you have purchased from your electricity supply company.
The kilowatt hour (KWHr) measures electricity use.
To calculate the average energy consumption in kilowatt-hours per square meter per day for a specific location, you can divide the total energy consumption in kilowatt-hours by the total area in square meters and the number of days. This will give you the average energy consumption per square meter per day.
The typical consumption of kilowatt-hours per square meter per day in a residential building is around 10 to 15 kWh/m/day.
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.
An electricity meter
A wattmeter measures power, which is the rate of doing work, expressed in watts.An energy meter measures the amount of energy consumed, usually in kilowatt hours.The meter on the wall of your house is an energy meter.
These do not have the same units. 1 kilowatt hour per meter cubed is in kg m-1 s-2 1 kilojoule per kg is in m2 s-2
