How do you calculate kWh of energy?

How much is 1 KW per Hour

Think of kWh (kilowatt-hour) as a simple way to measure how much electricity you use. You just take the power of your appliance (in watts), multiply it by how many hours you use it, and then divide by 1000. That’s it! For example, a 1000W (1 kW) appliance used for 1 hour = 1 kWh. This helps you easily understand your electricity bill and track usage at home.

Formula: E (kWh/day) = P (W) × t (hours/day) ÷ 1000
