The kilowatt-hour (kWh) is a unit of energy equivalent to one kilowatt (1 kW) of power expended for one hour (1 h) of time. Formula to calculate kilowatt hour. To calculate kWh, we multiply the power in watts by the number of hours and then divide by 1000 to get kWh First, determine the power usage of the air conditioning. And average central air unit likely runs at approximately 3500... Next, determine how long it will run for. We will assume a period of 7 days running 16 hours per day = 112 total hours. Enter the hours and power into the formula to calculate. To get the number of kWh, you just multiply the number of kW by the number of hours the appliance is used for. For example, a device rated at 1500 W that's on for 2.5 hours: 1500 Ã· 1000 = 1.5. That's 1.5 kW. 1.5 x 2.5 = 3.75. So, a 1500 W appliance that's on for 2.5 hours uses 3.75 kWh. How do I calculate kW to kWh A Kilo-watt hour helps electrical companies to measure how much energy is used within a property. kWh allows you to monitor your electrical and gas bills and understand how to find great deals when switching providers. In this blog, we will go into depth on what a kWh is and how this affects your energy efficiency within your home
