How to Calculate Kilowatt-Hours (kWh Calculation)
To get the number of kWh, you just multiply the number of kW by the number of hours the appliance is used. For example, a device rated at 1,500 W that''s on for 2.5 hours: 1500 ÷ 1000 = 1.5. That''s 1.5 kW. 1.5 x 2.5 = 3.75. So, a 1,500 W appliance that''s on for 2.5 hours uses 3.75 kWh.
