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.

To calculate the cost of running a 1000-watt device for 12 hours, you need to know your electricity rate per kilowatt-hour (kWh). Multiply the device’s wattage by the hours of use, then divide by 1000 to get the total kilowatt-hours used. Finally, multiply the kilowatt-hours by your electricity rate to get the cost.

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 a 1000 watt light bulb in 24 hours?
The cost to run a 1000 watt light bulb for 24 hours is dependent on your electricity rate. Assuming an average rate of $0.12 per kilowatt-hour, it would cost $12 to run the light for 24 hours (1000 watts = 1 kilowatt).
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 will it cost to run a 185 watts per day?
To calculate the cost of running a device that consumes 185 watts per day, you need to know the cost of electricity per kilowatt-hour. Assuming an average cost of $0.12 per kWh, running a 185-watt device for 24 hours a day would cost about $0.50 per day (185 watts / 1000 * 24 hours * $0.12).
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 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.

What does it cost to run a 5.8 amp motor at 120 volts?
To calculate the cost of running a 5.8 amp motor at 120 volts, you need to know the cost per kilowatt-hour (kWh) of electricity. Multiply the motor's amperage by the voltage to get the power consumption in watts (5.8 amps x 120 volts = 696 watts). Then divide the watts by 1000 to convert to kilowatts (696 watts / 1000 = 0.696 kWh). Finally, multiply the kWh by the cost per kWh to determine the running cost.
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 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.
How much wattage does a standard cartridge heater usually require to run?
A standard cartridge heater usually requires between 1000 and 11,500 watts to run. They run on 120 or 240 volts and one can find more information on the Chromalox website.
