A kilowatt hour is calculated by adding the watts together and deviding by 1000, this will give you kilowatts (kW). Then work out how many hours you are using this load for. multiply the kW by the hours and you get kWh. eg 15 lamps at 100w = 1500w/1000 = 1.5 kW. If these were left on for 6 hours then 6 x 1.5 = 9 kWh.
Answer
There is no such thing as a 'kilowatt per hour'. It's rather like saying 'kilometres per hour per hour', because a kilowatt is a special name given to a joule per second -in other words, it measures a rate.
To convert watts to kilowatts, you divide by 1,000. Therefore, 500 watts is equal to 0.5 kilowatts. To convert minutes to hours, you divide by 60. So, 500 watts per minute is equivalent to 0.5 kilowatts per 60 minutes, or 0.5/60 = 0.00833 kilowatts per hour.
To calculate the cost per hour, we first need to convert the power consumption from amps to kilowatts. We can do this by multiplying the current (amps) by the voltage (110 volts). Next, we convert kilowatts to kilowatt-hours by dividing by 1000. Finally, we multiply the result by the cost per kilowatt-hour ($0.10911) to get the cost per hour of running the appliance.
To calculate the cost of operating the 1350 watt heater, first convert the watts to kilowatts by dividing by 1000 (1350 watts = 1.35 kW). Next, calculate the hourly cost by multiplying the kW by the electricity rate ($0.07 kWh). Finally, multiply the cost per hour by the number of hours the heater is used per day to determine the daily operating cost.
None. There is no such thing as a 'kilowatt per hour'. If, on the other hand, you are asking how many 'kilowatt hours' a flatscreen television uses, simply look at its nameplate to find its power rating in kilowatts (more likely, it's in watts, so you need to divide by 1000), and multiply it by 1 to find the number of kilowatt hours consumed over a period of one hour.
To convert hours per month to kilowatts per hour, you would need to know the energy consumption for that month. Once you have the total energy consumption in kilowatt-hours for the month, you can divide it by the total number of hours in that month to get the average kilowatts per hour. This will give you the average power consumption rate over that month.
To convert watts to kilowatts, you divide by 1,000. Therefore, 500 watts is equal to 0.5 kilowatts. To convert minutes to hours, you divide by 60. So, 500 watts per minute is equivalent to 0.5 kilowatts per 60 minutes, or 0.5/60 = 0.00833 kilowatts per hour.

kW or kilowatts are power and not interchangeable with speed
10000 BTU per hour is equivalent to approximately 2.93 kW.
To calculate the energy generated by a solar panel in one hour in kilojoules, you would need to know the power output of the solar panel in kilowatts. You can then convert kilowatts to kilojoules by multiplying by 3,600 (since 1 kilowatt-hour is equal to 3,600 kilojoules). This calculation will give you the energy generated by the solar panel in kilojoules per hour.

Next, calculate the hourly cost by multiplying the kW by the electricity rate ($0.07 kWh). Finally, multiply the cost per hour by the number of hours the heater is used per day to determine the daily operating cost.
No device uses "kilowatts per hour". A watt or kilowatt is a unit of power, not of energy. That means that the "per hour" or "per second" is already implied - the watt refers to a "rate of energy conversion" - not to an amount of energy. If a devices uses a certain amount of kilowatts, it uses this amount all the time while it is on - whether it is kept on for a second or for several days.

To convert hours per month to kilowatts per hour, you would need to know the energy consumption for that month. Once you have the total energy consumption in kilowatt-hours for the month, you can divide it by the total number of hours in that month to get the average kilowatts per hour. This will give you the average power consumption rate over that month.
Miles per hour or kilometers per hour
about $33 an hour
1 miles per hour = 1 609.344 meters per hour
