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.
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.
What unit of electricity measures is used to measure the power consumption of a device?
The kilowatt hour (KWHr) measures electricity use.
What measures gas and electricity usage?
The usage is measured by gas and electricity meters. A gas meter measures the volume of gas passing through. An electricity meter is an energy meter which measures the kilowatt-hours use.
How much electricity does the average person use in a day hour wise?
How much electrical energy does the average person use in a day . . . In the UK the figure is about 16 kilowatt hours.
How much does 40 kilowatt bulb use in 1 hour?
Anything that uses 40 kilowatts would use 40 kilowatt-hours for each and every hour.
A 1500 watt heater how much will it cost to run per hour?
Electricity is sold to consumers thru meters that record kilowatt hours: 1000 watts turned on for 1 hour= 1kwh or kilowatt hour. If cost for 1 kwh = $0.10, then 1500 watts for 1 hour would cost 15 cents. Varies by location of the country. Check your utility bill for exact cost per kwh.
How much does one kilowatt cost?
Well if you think about it you can't really sell electricity so therefor it dosent really have a price but I'm pretty sure you weren't going to try and stik it in a bottle and sell it right
How are residential consumers charged for electrical service?
In general, the electrical service is routed through a meter, which keeps track of the current flow over time. The line voltage is "known" and that plus the current flow is used to calculate power. Power, which is volts (voltage) times amps (current), is measured in watts. A watt isn't really that big in home energy use, so we look at them in groups of one thousand. A thousand watts is a kilowatt, or kW. If you use a kW for one hour, you have used a kilowatt hour (kW hour) of electricity. And you are sold the electricity by the kilowatt hour.
