Best Answer: A microwave oven putting out 900 watts consumes around 1500 watts. One unit of electricity is 1 kilowatt-hour, so a 1500 watt appliance will use 1.5 kWh or 1.5 units. Electricity is about 7p per unit, so it will cost around 11p to run it continuously for 1 hour.
To figure how many kilowatts an appliance uses, take the wattage of the appliance, multiply it by the number of hours used, and divide by 1,000. For example, if a new refrigerator has a wattage of 300, multiplied by 730 hours, and divided by 1,000, it averages 219 kilowatt hours.Ad.The price of a kilowatt hour varies in the US, depending on location and peak usage times, but on average, one kilowatt hour costs about $0.06 USD.Electric bills will usually state exactly how many cents are being charged per kilowatt hour, which can help determine the cost of running an appliance.he price of a kilowatt hour varies in the US, depending on location and peak usage times, but on average, one kilowatt hour costs about $0.06 USD.
