1 kW x 12 hours = 12 kWh. As to the cost - that may vary from country to country. Look at a bill from the power company to see how much they charge you per kWh. If that is not explicitly stated, divide the total amount of the bill, by the number of kWh used.

How much does it cost to run a 5 watts transformer?
If the transformer uses 5 watts per hour you need to know what you are paying per 1000 watts from your power company. If you pay lets say $3.00 for 1000 watts then when your transformer burns 1000 watts it cost you $3.00 your cost will be $3.00 for 200 hours run time.
How much does it cost to run electric 185 watts per hour?
185 watts will use up 185 watt-hours every hour. That is 0.185 kilowatt-hours each hour, costing about £0.03
Which appliance will use the most energy if it is run for 15 minutes?
Two formulas are needed to calculate the answer:[Energy (watt-hours)] = [Power usage rate (watts)]? x [Time (hours)]and[Power usage rate (watts)] = [Voltage (volts)] x [Current (amps)]?
What does 5 watt hours means in terms of battery use for a camcorder?
It means you can run whatever off the battery as long as power x time = 5. Ten watts for 0.5 hours. Five watts for 1 hour or 2.5 watts for 2 hours.
How much does it cost to run a 40 watt heater for 24 hours?
40 watts for 24 hours is 40 x 24 watt-hours, or 960 watt hours which is 0.96 kilowatt-hours, equal to 0.96 Unit, which costs about £0.12.

About how much does a 60w heat lamp that's on 12 hours a day cost per month to run in the UK?
60 (watts) x 12 (hours on) x 30 (days per month) = 21600 (watt-hours) 21600 / 1000 = 21.6 killowatt hours X your electric providers price = $$$
How much does it cost to run electric 185 watts per hour?
185 watts will use up 185 watt-hours every hour. That is 0.185 kilowatt-hours each hour, costing about £0.03
How much does it cost to run a computer for 50 hours in a week if the monitor runs on 140 Watts and the tower runs on 260 Watts and the Electric Company charges 11.2 cents per kilowatt-hour?
It would cost $2.24 in electricity to run the computer 50 hours in a week.
How much does it cost to run a light bulb?
It depends on the bulb, how many watts it is. All bulbs are marked with the correct voltage and the power taken, in watts. You multiply the watts by the number of hours to find the watt-hours of energy used. Then divide by 1000 to find the kilowatt-hours. A kilowatt-hour is also called a unit and you pay about £0.15 for a unit of electricity. Let's say it's a 100 watt bulb running for 24 hours. That uses 2400 watt-hours or 2.4 kilowatt-hours, which costs about 2.4 x £0.15 which is £0.36.
Which appliance will use the most energy if it is run for 15 minutes?
Two formulas are needed to calculate the answer:[Energy (watt-hours)] = [Power usage rate (watts)]? x [Time (hours)]and[Power usage rate (watts)] = [Voltage (volts)] x [Current (amps)]?
How do you calculate gallons per hour from wattage on a pump?
Pumps don't have wattage but the motors that drive them do. motors are rated in amps and volts. if you multiply amps times volts you get watts. Gallons per hour are listed on pumps or can be measured by running the pump for a calculated time and measuring the gallons. Run the pump 1 min and measure the water and multiply by 60 and you have gallons per hour. A kilowatt/hour is the equivalent of using 1000 watts for one hour, 100 watts for 10 hours, or even one watt for 1000 hours. Any combination of watts times hours that equals 1000, is one kilowatt/hour's worth of power used. (Wiki)
How much does it cost to run a 1000 watt light bulb in 24 hours?
a 1000 watt bulb used for 24 hours consumes 24,000 watt-hours of energy, or 24 kilowatt-hours or kWh. That is also described as 24 Units, each costing around £0.15. So the toal cost would be about £3.60.
What does 5 watt hours means in terms of battery use for a camcorder?
It means you can run whatever off the battery as long as power x time = 5. Ten watts for 0.5 hours. Five watts for 1 hour or 2.5 watts for 2 hours.
How much does it cost to run a 40 watt heater for 24 hours?
40 watts for 24 hours is 40 x 24 watt-hours, or 960 watt hours which is 0.96 kilowatt-hours, equal to 0.96 Unit, which costs about £0.12.
What uses more electricity a 1000 Watt Halogen heather or a small heatpump?
A small heatpump is unlikely to need as much as 1000 Watts but check the rating plate to get the power. If the heatpump takes less than 1000 Watts then the 1000 Watt halogen heater is the answer. NOTE: That answer is only correct if these things are run continuously for 24 hours a day, 7 days a week. If you only switch the halogen heater on for one hour every 24 hours then it will only use 1000 WattHours (1 kWh) of energy in that period of 24 hours. If a heatpump runs for 24 hours, and it takes 100 Watts, then the heatpump will be taking 2400 WattHours (2.4 kWh) of energy! You will now (hopefully!) understand why that Note is relevant: when you wish to compare the energy costs of running two different appliances, to make a fair comparison you have to consider the actual running times as well as the bare Wattage.
How many kilowatts does it take to run an Xbox?
It varies, depending on the model.According to the website energyusagecalculator.com: * Xbox One uses 70-120 watts. * Xbox 360S uses 90 watts. * Xbox 360 original uses 180 watts. So, much less than one kilowatt, which means 1000 watts. If you want to convert the watts to kilowatts, you can divide the watts by 1000. You can also use the website mentioned, to figure out the actual money cost - which will depend not only on the power, but also on how long you use a device.
