The way that watts are calculated is volts x amps. Watts will be the result of any voltage x any amperage. It doesn't matter what the countries voltage is, the wattage is constant. Amps x volts over the hours will become very large so the number is divided by 1000 to keep the number compact. Using this number it is referred to as a kilowatt. The utility company sells power a a set price per kilowatt over a one hour time interval. In my area the charge is .07 cents for every kilowatt of power that gets used.
Additional AnswerElectricity meters measure the amount of energy you consume, expressed in kilowatt hours for historical/traditional reasons. These days, with the widespread use of the SI system, it would make more sense to measure electrical energy in kilojoules or megajoules, enabling one to accurately compare the cost of electrical energy with other forms of energy, such as gas.

How many kilowatt hour make 1 watt?
1kilowatt = 1000 watts but you cannot compare a kilowatt hour to a watt, the extra dimension of time changes what is being measured. The watt is a measure of power. The watt second and the kilowatt hour is energy. The misunderstanding comes from our use of the term POWER COMPANY for our electricity suppliers. They bill us in kilowatt hours which is energy, not power.
How many kilowatt-hours of electricity are used by two 60 W electric blankets used for 9 hours?
In each hour two 60W blankets will use 120W. 120W for 9 hours = 1080 W or 1.08 Kilowatts.
How do you calculate meters per second to miles per hour?
Use this conversion: meters per second x 2.237 = miles per hour
How do you convert gallons per minute to cubic meters per hour?
Use this formula: gallons per minute x 0.227 = cubic meters per hour
How many kilowatt-hours does a 50 watt fluorescent light bulb use in 24 hours?
50 watts is 0.05 kilowatts, so in 24 hours it uses 0.05 x 24 kilowatt-hours, or 1.2 kilowatt-hours of energy.
Where do you use Kilowatt Hour?
Measuring electricity usage.
What does one unit of electricity mean in watts?
A unit (as mentioned on the electricity bills) is represented in kWH or Kilowatt Hour. This is the actual electricity or energy used. If you use 1000 Watts or 1 Kilowatt of power for 1 hour then you consume 1 unit or 1 Kilowatt-Hour (kWH) of electricity.
How do you calculate the electricity bill per month for a house?
To calculate the electricity bill for a house per month, multiply the total kilowatt-hours used by the cost per kilowatt-hour. The total kilowatt-hours used can be found on your electricity bill or by monitoring your meter. The cost per kilowatt-hour is provided by your utility company.
What is the electricity usage of a power Circular saw?
It depends on the power rating of the saw. If it is a 1 KW (Kilowatt) saw then it will use 1 KWH (Kilowatt hour) of electricity for every hour it is used. This is equivalent to 1 unit of electricity. If it is 500 W (Watt) then it will use half this. If it is 2 KW it will use double this.
What is the unit of measurement for electricity consumption?
Electricity consumption or, more accurately, energy consumption is measured in units called joules (J), although electricity supply companies use a bigger, non-SI, unit called the kilowatt hour. A kilowatt hour is defined as 'the energy consumer, over a period of one hour, at the rate of one kilowatt'.
How many kilowatt hour make 1 watt?
1kilowatt = 1000 watts but you cannot compare a kilowatt hour to a watt, the extra dimension of time changes what is being measured. The watt is a measure of power. The watt second and the kilowatt hour is energy. The misunderstanding comes from our use of the term POWER COMPANY for our electricity suppliers. They bill us in kilowatt hours which is energy, not power.
How much electricity costs when a light bulb is on for a long period of time?
The cost of electricity for a light bulb being on for a long time depends on the wattage of the bulb, the electricity rate per kilowatt-hour, and the duration it is on. To calculate the cost, you can use the formula: (Wattage of bulb / 1000) * hours on * cost per kilowatt-hour.
What unit of electricity measures is used to measure the power consumption of a device?
