To calculate an answer, first multiply the watts used by the hours of use. This will give you watt hours. Now divide your answer by 1000 and this will give you kWh of use. Take the kWh of use and multiply it by the cost per kilowatt that your utility company charges you per kilowatt hour. This information can be found on your electric bill or you can give them a call and ask how much they charge you per kilowatt hour.
To calculate the watts on your electricity bill, you would need to look at the wattage of each electrical device in your home (which can usually be found on the device itself or in the user manual) and the number of hours each device is used per day. Multiply the wattage by the number of hours used per day to calculate the watt-hours for each device, then sum all the watt-hours to get the total watts consumed over a billing cycle.
Look at kilowatt hours on your bill. Each of those is 1000 watts per hour.
To calculate the electricity bill for a house per month, multiply the total kilowatt-hours used by the cost per kilowatt-hour. The total kilowatt-hours used can be found on your electricity bill or by monitoring your meter. The cost per kilowatt-hour is provided by your utility company.
The average KWH is 0.1099 per hour. In order to determine how an electric bill is calculated for a home is to use an online calculator. This will explain how much electricity is used by different things in your home.
The 12 v light should have the voltage and the power in watts printed on it. When it is running, it uses that amount of watts continuously. The energy is measured by the watt-hours, in other words the watts multiplied by the number of hours it runs for. 1000 watt hours makes 1 kilowatt-hour, which is a Unit on the electricity bill.
The unit of energy in an electricity bill is a kilowatt-hour, also known as a Unit. To calculate the energy in units, multiply the power in kilowatts by the time in hours.

To calculate the electricity bill for 60 kWh, you would multiply the number of kilowatt-hours (60) by the rate charged per kilowatt-hour by your utility company. The result will give you the total cost for that amount of electricity consumed.
1500 watts... Average electric bill is $0.98/ killowatt hour (1000 watts an hour) So it wil cost around $1.50- $2.00/ Hour to operate
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.
A power of 10 kW or 10,000 watts means that 10,000 Joules of energy is converted every second. In 1 hour the energy expended is 10 kilowatt-hours which would appear as 10 units on the electricity bill.
It depends on the voltage. On a 120 v system that is a power of 540 watts, so the units used per day are 0.54 x 24, or 13 units.
