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.
Once you know the kilowatts used per hour and the cost of kilowatts per hour, plug in the number of hours you plan to use the heater each day. For example, a 1,500-watt portable space heater that runs for 12 hours a day at a rate of $0.10 per kilowatt hour will cost $1.80 per day.Hereâs how it looks: 1.5 Kilowatts Used Per Hour X $0.10 kWh X 12 hours = $1.80 a day.or example, a 1,500-watt portable space heater that runs for 12 hours a day at a rate of $0.10 per kilowatt hour will cost $1.80 per day.
