technically, a kilowatt - hour is the amount of electrical power dissipated by an circuit or appliance over the period of one hour, and it is the number that shows up on my electric meter that the power company reads to figure out my bill. More practically, if I am looking at a light bulb (or any other appliance) that is stamped 100W, that bulb will use 100 watts (or 0.1 kW) of power for each hour it is on. The calculation looks like: .1kW x 1hr = .1kWh Of course if I only turn it on for six minutes, I use the power for only one tenth that hour, so .1kW x .1hr = .01kWh or 10 Watt-hours. Things like dishwashers and refrigerators turn on and off, and are rated for an average hour of use under average conditions.

∙ 13y agoWatts is power. kWh is energy. You have to know the length of time (h) over which the energy (kWh) was expended or produced (how long it took to convert the energy).
If you divide the energy (kWh) by time (hours), you get the power, in kW. Then, simply divide kW (kilowatts) by 1000 to get Watts. Power is the rate of energy conversion.

How many kwh is mwh?
1 mwh = 1000 kwh hence 4 mwh = 4000 kwh
927.7 million kWh to gwh?
1 million kWh = 1 GWh, so 927.7 million kWh = 927.7 GWh.
How much is kWh x 100000000?
The answer to this question is zero. There is no kWh given.
How many kWh if use a light with 32 watt and 220 V?
To find kWh a time frame has to be given. That is what the h in kWh stands for.
How many KWh does an average 3000 squ house use?
about 10,000 KWh
If the meter on the power box reads 407khw how does that cost?
Multiply the figure by your cost per kwh. The kwh cost is available from your local power company or utility. For instance, if a kwh was priced at 7.6 cents/kwh, then the total cost would be a bit over $30.
What is fullform of kwh?
KWH
What is the btu value of 341744380 kwh divided by 508068160 kwh?
0.6726
How many kwh is mwh?
1 mwh = 1000 kwh hence 4 mwh = 4000 kwh
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 do you find out how much an air compressor costs you in electric?
To continue my question...I just found out that the tenant that rents out the garage is using the electrical outlet to plug in all sorts of tools to repair his cars. One of them is an air compressor.I do not want to confront him until I can figure out a ballpark figure of what it is costing me.I have to somehow convert the specifications of the compressor into KWH so I can get an idea of how to do the equation, but I have no clue as to how to do this.I also do not know what specific air compressor he has, so I will use the specifications of one from the Sears site as a basic estimate. If he is using a 2 Horsepower compressor, how do I figure out the KWH? My electric bill says it costs me KWH @ $ .0859.Can someone give me a simple equation to figure out the cost per hour of a basic compressor.

How many KWH does dinorwic power station make?
Dinorwig is a 'pumped storage' hydro power facility. It has a capacity to produce 1.89GW of electricity, which equates to 6.8TWh. I terms of kWh, this would be 6.8E9 kWh or 6,800,000,000 kWh. (6.8 billion kWh).
Diesel grams per kwh?
Typically you would use 0.276 litres/kWh for HSD and 0.234 litres/kWh for HFO
927.7 million kWh to gwh?
1 million kWh = 1 GWh, so 927.7 million kWh = 927.7 GWh.
