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.
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.
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.
1 kilowatt hour = 3,600,000 Joules 1 Tetrajoule = 1,000,000 Joules 1 kilowatt hour = 3.6 Tetrajoules
A 30-watt bulb uses 0.03 kilowatt-hours every hour, or 30 kilowatt-hours in 1000 hours. To find the kilowatt-hours, multiply 0.03 by the time in hours.
Multiply by kilovolts, and you will have it. For example: 1 amp hour X 0.120 kilovolts = 0.120 kilowatt hours

kWh = Power(kW) x Time (hours)AnswerA kilowatt hour (symbol kW.h) is a unit of measurement of electrical energy.
It is not power which is measured in homes, but energy consumption. Electricity companies charge for energy consumption in kilowatt hours (kW.h). This is done using an energy meter (also known as a 'watt-hour meter' or 'kilowatt-hour meter'), which monitors the supply voltage, and the in-phase component of the load current.
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.
Anything that uses 40 kilowatts would use 40 kilowatt-hours for each and every hour.
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.
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.
