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)
The number of appliances that can be used in 3.5 kWh depends on the energy consumption of each appliance. To calculate, divide 3.5 kWh by the average energy consumption of each appliance in kWh to determine how many can be used.
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.
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
To calculate the cost of electricity for using a 1000-watt (1 kW) appliance for 12 hours, first determine the total energy consumed: 1 kW × 12 hours = 12 kWh. Then, multiply the total energy by your local electricity rate (e.g., $0.12 per kWh). For example, at $0.12 per kWh, the cost would be 12 kWh × $0.12 = $1.44.
To calculate the cost per kWh given 35 kWh of usage and the total cost, divide the total cost by the number of kWh. For example, if the total cost is $70 for 35 kWh, the cost per kWh would be $70 / 35 kWh = $2 per kWh.
The number of appliances that can be used in 3.5 kWh depends on the energy consumption of each appliance. To calculate, divide 3.5 kWh by the average energy consumption of each appliance in kWh to determine how many can be used.

The equation to calculate the amount of energy used by an appliance is: Energy (kWh) = Power (kW) x Time (hours). Multiply the power consumption of the appliance in kilowatts by the number of hours it's used to find the total energy consumed in kilowatt-hours.
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.

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.
First find how many kw are being used. For example, two items using 0.5 kw each add to 1 kw. Then, multiply by the hours it is being used. If we ran these two items for 1 hour we would end up with 1 kwh.
To calculate the cost of electricity for using a 1000-watt (1 kW) appliance for 12 hours, first determine the total energy consumed: 1 kW × 12 hours = 12 kWh. Then, multiply the total energy by your local electricity rate (e.g., $0.12 per kWh). For example, at $0.12 per kWh, the cost would be 12 kWh × $0.12 = $1.44.
None if your plugged in to the neighbors electricity!!
The cost of electricity in rupees for a 1000-watt (1 kW) appliance depends on the local electricity tariff, which varies by region and provider. To calculate the cost, you can multiply the power consumption (in kW) by the number of hours used and then by the rate per unit (kWh) charged by your electricity provider. For example, if the rate is 5 rupees per kWh and the appliance runs for 1 hour, it would cost 5 rupees.
To calculate the cost per kWh given 35 kWh of usage and the total cost, divide the total cost by the number of kWh. For example, if the total cost is $70 for 35 kWh, the cost per kWh would be $70 / 35 kWh = $2 per kWh.
P.F = Kwh/Kvarh
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.
