Your question reminds me of the most important lesson my intro to engineering professor taught us. The answer to every question is, "well that depends." This one seriously depends. Your location, house size, appliance configuration, and living habits will all have dramatic affects on your electical usage. I think my bills up in Alaska ranged from an average of 5-10 kW average to 35+ in the winter.
1 kilowatt hour = 3,600,000 Joules 1 Tetrajoule = 1,000,000 Joules 1 kilowatt hour = 3.6 Tetrajoules
Multiply by kilovolts, and you will have it. For example: 1 amp hour X 0.120 kilovolts = 0.120 kilowatt hours
Watt, kilowatt, or megawatt are units of power (energy/time). A watt is 1 joule/second. A kilowatt is a thousand joules per second. A kilowatt is also 1 kWh/hour (kilowatt-hour / hour). Since you would usually pay per kilowatt-hour, you might be more interested in the number of kilowatt-hours. A megawatt is a million joules per second - or a thousand kWh/hour.
a kilowatt hour measures electrical usage in the home usually 600 to 1200 kwh for the average home
If a kilowatt-hour is 10 cents, then 3.9 billion kilowatt-hours (billion meaning 109) has a value of 0.390 million dollars, or 390 million dollars.
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.
There is no such thing as a "kilowatt per hour". Kilowatt is a unit of power, not of energy. A unit of energy is kilowatt-hour. That's kilowatt times hours, not "per" hour ("per" implies division, not multiplication). If a generator produces 10 kilowatts, that means it produces 10 kilowatt-hours every hour.
1 kilowatt hour = 3,600,000 Joules 1 Tetrajoule = 1,000,000 Joules 1 kilowatt hour = 3.6 Tetrajoules
A 40 kilowatt bulb consumes 40 kilowatt-hours of energy in 1 hour. This means it uses 40 kilowatts of power for one hour (40 kW x 1 hour = 40 kWh).
Multiply by kilovolts, and you will have it. For example: 1 amp hour X 0.120 kilovolts = 0.120 kilowatt hours
Watt, kilowatt, or megawatt are units of power (energy/time). A watt is 1 joule/second. A kilowatt is a thousand joules per second. A kilowatt is also 1 kWh/hour (kilowatt-hour / hour). Since you would usually pay per kilowatt-hour, you might be more interested in the number of kilowatt-hours. A megawatt is a million joules per second - or a thousand kWh/hour.
Watts does not have a time component to it; so you should have asked, "How many kilowatt-hours does an oven use per hour?' For example, if the oven uses 1600 watts, then in one hour, it would use 1600 watt-hours, or 1.6 kilowatt-hours.
watts or kilowatts are used to measure power, which is how quickly energy flows, and electrical energy is measured in kilowatt-hours. A kilowatt-hour is also known as a Unit of electrical energy, and it is the amount of energy used when a power of 1 kilowatt flows for 1 hour.
No, kilowatt-hours are an exact measure of a quantity of energy. Energy is something that can be measured exactly and if you have an electricity supply at your house there is a meter that measures the kilowatt-hours you use. If you have a 40-watt light, it uses 40 watt-hours if it is on for an hour. If it is left on for 24 hours it uses 40 x 24 watt-hours, which is 0.96 kilowatt-hours, that might cost you 10-20 cents or pence.
First find your watt hours and by moving the decimal place change to kilowatt hours. Then multiply that answer by .07 cents per kilowatt hour.
Kilowatt hours (kWh) is a unit of energy equal to the consumption of one kilowatt of power for one hour. It is commonly used to measure electricity consumption and is found on utility bills to indicate how much energy has been consumed over a period of time.
The kilowatt hour is just a unit of measurement for energy, it isn't bad for energy in any way.
