The cost of electricity per kilowatt-hour varies depending on location, time of day, and energy provider. In the United States, the average cost is around 13 cents per kilowatt-hour. However, this can range from around 9 cents to 20 cents or more, depending on factors such as renewable energy programs, demand charges, and taxes.
The kilowatt is a unit of power (energy / time); the kilowatt-hour is a unit of energy - the energy equivalent to the power of 1 kW, during one hour. The kilowatt-hour is equivalent to 3.6 x 106 Joule (a Joule is the same as a Watt-second).
The kilowatt-hour is commonly used as a unit to charge for electrical energy. Note that you pay for electrical energy, not for electrical power.
The official SI unit for energy, of course, is the joule; but the kilowatt-hour (equal to 3.6 million watt-seconds, i.e., 3.6 million joules) is used traditionally, probably for historical reasons. It is fairly easy to use in calculations (e.g., if you use a 0.5 kW device for 4 hours, you use 0.5 x 4 = 2 kWh of energy). Scientists may prefer to switch to joules (or megajoules; 1 kWh = 3.6 MJ), but this is unlikely to change. Common people are more comfortable doing this type of calculations by the hour than by the second.
One kilo hour equals to one hour. This is used in energy.
185 watts will use up 185 watt-hours every hour. That is 0.185 kilowatt-hours each hour, costing about £0.03
Approximately 5 kilowatt hours. Check your electric bill to see what you are charged per kilowatt hour.
To calculate the monthly cost, first convert the daily usage into monthly usage: 700 watts * 10 hours * 30 days = 210,000 watt-hours or 210 kWh. Then, calculate the monthly cost: 210 kWh * $0.09/kWh = $18.90. So, the monthly cost of using the refrigerator would be $18.90.
1 kilowatt-hour is 1000 watt-hours and 60 watt bulb consume during 1 hour 60 watt-hours of electricity, so then it costs 0.6 cent =>60/1000=0,06*price of 1 kilowatt-hour = 0.6 cent
MW is a unit of power just like kW 1MW = 1000 kW 1 mega-watt = 1000 kilo-watt Watt is a measurement of power. watt-hour is a unit of energy 1 mega-watt-hour = 1000 kilo-watt-hour
This is usually very cheap, $0.03-$0.08 or even less
The average for america is about 18 cents per kilo-watt hour, 0.18, multiplied by the 9 watts it consumes, 0.009 because we are using KILO-watt hours, to give you a grand total of: 0.162 Cents per hour to run
A Joule is a Watt-second. 2 kilo-watt-hours are 2 x 1000 x 3600 watt-seconds (since kilo means 1000, and an hour has 3600 seconds).A Joule is a Watt-second. 2 kilo-watt-hours are 2 x 1000 x 3600 watt-seconds (since kilo means 1000, and an hour has 3600 seconds).A Joule is a Watt-second. 2 kilo-watt-hours are 2 x 1000 x 3600 watt-seconds (since kilo means 1000, and an hour has 3600 seconds).A Joule is a Watt-second. 2 kilo-watt-hours are 2 x 1000 x 3600 watt-seconds (since kilo means 1000, and an hour has 3600 seconds).

It depends on how much you waste.It depends on where you live and how much the local public utility that supplies electricity charges per KwH -- kilo-watt hour.
I believe you are thinking of a watt perr hour or more commonly used is a kilo-watt-hour - that's the amount of power used in an hour, not exactly how much work is done however.
185 watts will use up 185 watt-hours every hour. That is 0.185 kilowatt-hours each hour, costing about £0.03
1000watts=1kilowatt
A single bar of an electric fire usually consumes 1000 Watts or 1 Kilo Watt (kW) Run the bar for 1 hour and you use 1 KW/Hour (1000 Watts for 1 hour) Refer to your last electricity bill where your supplier will list their charges in KW Hrs. I would imagine around 25 cents? per Kwh
It depends, If you measure your own energy it would be in joules, if it is for your house you measure it with kilo-watt hour
