About .6 kilowatts per hour.

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.

There is no such unit as a 'watt per minute' or a 'kilowatt per hour'.

1.5 Kw

Although I do not know the exact number, it would be low if measured in kilowatts. The electric company charges by how many kilowatts a house uses per hour.

To obtain watts you need amps x volts.

Same as in a second, or in a century. A kilowatt is a unit of power, not of energy.

watt (w) means joules per second. kW (kilowatts) means thousands of joules per second. Multiply that by 3600 to get the joules used per hour.

10,000 BTUIT/hr is about 2.93 kW

kW or kilowatts are power and not interchangeable with speed

The price of electricity is usually quoted per kilowatt-hour. If your hair dryer uses 2,000 watts for 30 minutes, that is one kilowatt-hour.So take the wattage rating of your hair dryer and divide by 1000 to get kilowatts. You specified 30 minutes, which is 0.5 hours; multiply the kilowatts by the hours to get kilowatt-hours. Then multiply the price per kilowatt-hour of your electricity to get the total cost.For example: 1500-watt hair dryer for 30 minutes at $0.12/kW-h1500 watts Ã· 1000 = 1.5 kilowatts30 minutes = 0.5 hours1.5 kilowatts x 0.5 hours = 0.75 kW-h0.75 kW-h x $0.12/kW-h = $0.09
