What is a Kilowatt (kW) and Kilowatt Hours (kWh) and Unit of Electricity
The difference between kW and kWh can really help you understand and monitor your electricity bills.
The key difference between kWh and kW is what they measure.
A Kilowatt is 1,000 watts, and is simply a measure of how much power an electric appliance can consume.
You can quickly convert watts (W) to kilowatts (kW) by dividing your wattage by 1,000:
A Kilowatt Hour measures the energy an appliance uses in kilowatts per hour.
For example, if you have a 2,000 watt (2kW) washing machine and it runs for two hours 2 kWh’s of energy. Likewise, if it runs for 30 minutes, you will use 1kW of energy.
The difference between kWh and kW, and what you see on your bill, is that kW reflects the rate of electricity you use, and kWh indicates the amount of electricity you use.
