Well, a 120V appliance that draws 15A would be using 1800W. (15x120). A killowatt hour is one killowatt used continuously for an hour. If you used that device for one hour straight, it would use 1.8 kWh. (Keep in mind the device may not draw a full 15A)

How do you calculate 3 phase motor kWH where voltage are 440 and amps are 11?
To calculate kWh a time component is needed for the hours.
How do you convert 400 amp of three phase supply into kwh?
By knowing the voltage you could use calculate the wattage. Power equals volts times amps. Divide by 1000 to get kilowatts.
Calculate electricity usage?
Watts x hours/1000 = Kwh Kwh x your electricity cost ($/Kwh) = $ For example: If you run a 60 watt light bulb for 8 hours and your electricity rate is $0.12/Kwh: 60 x 8 / 1000 = 0.48 Kwh x $0.12 $/Kwh = $0.576, or about 6 cents. This calculation works for any appliance, the watt usage is usually listed on the appliance
How do you Calculate electricity bill for 60 KWh?
Call your supplier, find out how much for one kWh, then 60 x that price.
How much does a 110 volt 12 amp appliance cost per month with 9 cents per kWh?
Use this formula to arrive at the wattage used. W = A x V. Now figure out how many hours there are in a month. Days (30 or 31) x 24 (or the number of hours the appliance is on per day) will give you this answer. Take that answer and multiply it by 9 cents or .09 for your answer.
How do you calculate the monthly running costs of electrical appliances?
When you get your electric bill, look to see how many kilo watt hours (kWh) you used for the month. Then how much the bill cost. take the price divided by the (kWh). This is truly what your paying per (kWh). One (kWh) is 1000 watts being used for a hour, so one 100 watt light being used for 10 hours = 1 (kWh) or a 1500 watt hair dryer being used for an hour = 1.5 (kWh). so if your appliance power use is listed in amps, take amps x volts to figure out the watts. Plus determine how often the appliance runs. this will give You an idea of cost.

How many KWh does a clothes dryer use?
None if your plugged in to the neighbors electricity!!

How you calculate import Kvarh in percentage?
P.F = Kwh/Kvarh
How many kWh in a cubic meter of water?
kWh stands for kiloWatthours, the amount of electrical energy an appliance uses or generates in one hour measured in kiloWatts. It has nothing to do with one cubic metre of water.

How much power is in a 120V line?
Most 120 Volt appliances have their Watts listed somewhere on the appliance. Divide this number by 1,000 to get kilowatts. Determine the rate you are charged for electric power. Your electric bill will tell you how many kWh(kilowatt hours) you use, and what the total charge is. Divide your total charge ($?) by the kWh used. In northern Illinois, we are charged about $0.11 per kWh. Multiply the number of hours the appliance is used by its power consumption in kilowatts. This gives you the number of kWh the appliance used. Then multiply that kWh value by the rate for your area that you determined from your electric bill. That will be the cost for the number of hours the appliance was on. Example: If I toast 2 slices of bread in my toaster, it takes about 3 minutes, or 0.05 hours. My electric bill is $61.38 and I used 558 kwh for that month. Dividing $61.38 by 558, I get about $0.11 per kWh. So, I divide my toaster Wattage (750) by 1,000 to get 0.75 kW. So now I can multiply the hours that the appliance was used (0.05) by its power consumption rate in kW (0.75). This result is 0.0375 kWh of energy used. Then I can multiply the rate the electric company charges ($0.11) by the energy used (0.0375 kWh). The final result is $0.004125.
How do you calculate boiler heat rate?
MCF * BTU = MMBTU MMBTU * KWH = Heat rate
How do you calculate KWH by KW and Running Hours?
You multiply the power by time, ie kW*h
