The Kilowatt hour (kW h) in Energy

What is Kilowatt hour (kW h)

The kilowatt hour (kWh) is a unit of energy commonly used to measure electricity consumption. It represents the amount of energy consumed when a power of one kilowatt (1 kW) is used for one hour. The concept is straightforward: if you have a device that uses 1,000 watts or 1 kilowatt of power, and you run it for one hour, it will use 1 kWh of energy. This unit is essential for understanding electrical energy bills, as it directly relates to how much energy a household or business consumes.

In mathematical terms, the kilowatt hour can be expressed using the formula:
