The standard unit of measurement of electrical consumption is the kilowatt-hour (KWH). It it simply the kilowatts multiplied by the hours. And a kilowatt is 1,000 watts. So, 100 watts x 24 hours = 2400 watt-hours, or 2.4 KWH.

∙ 12y agoWatts is a RATING of power not energy therefore 100 watts is a constant no matter how long its running for.. watt-hours is a rating of energy and after 24hrs 2.4kilo-watt hours have been used this is around 30-40p worth!!

∙ 9y agoElectricity in metric countries (USA and UK aren't metric) is charged in kilowatt hours.
To work out how much for the problem stated, mutiply the watts by the hours.
100 * 24 = 2400
watts * hours = watt hours
There are 1000 watts in a kilowatt, so to get kilowatt hours, divide by 1000
2400 / 1000 = 2.4
watt hours / 1000 = kilowatt hours
Answer is 2.4 kilowatt hours.
In non metric countries (USA and UK) , the energy unit is the calorie.
There are 859.845227859 calories in 1 watt.
So multiply 24 by 859.845227859 to get 20636.285468616 calorie/hours
Your energy utility may bill you in kilocalories, so divide by 1000
20636.285468616 calorie/hours / 1000 = 20.636285468616 kilo calorie/hours
Round it off to 20.64 kilocalorie hours.

The 'calorie' hasn't been used in the UK (well, other than in the food industry!) since I was in school, sixty years' ago!! The calorie was used in the centimetre-gram-second-ampere (cgsA) system, which has been obsolete for a great many years! It was superseded by the metre-kilogram-second-ampere (mksA) system and, since then, by the SI system (which is based on the mksA system). Energy, in the SI system is measured in joules.
Furthermore, the watt hour IS a metric unit. It's not an SI unit (that's the joule), but nevertheless, it is a metric unit.

How long wil 40w bulb glow in order to consume one unit of electricity?
A 40 watt bulb uses 40 watt-hours in an hour, which is 0.04 kilowatt-hours, so it would take 25 hours to use 1 kilowatt-hour or 1 unit.
How much energy does 100 w electric bulb consume in two hours?
energy consume by the bulb = P*time =100*6 wh =.6 kwhour=0.6 unit energy consume by the bulb = P*time =100*6 wh =.6 kwhour=0.6 unit
If a lamp bulb is rated at 100 watt why is a time factor not in the rating?
The unit watt is defined as energy per unit time. Thus a 100W light bulb consumes 100J of energy each second. Joules are a unit of energy. Watts are a unit of power.
What is the different between a 100 watt bulb and a 60 watt bulb?
40 watts of consumed power. The light output may be greater with one compared to the other, but wattage alone does not give us that information. Electric heaters, for example, consume 1500 watts of power and produce almost no visible light.Check the Lumen's. That is where the difference is.Current draw and light output.A 60 watt bulb uses 60 watts of electricity (i.e. it converts 60 joules of energy per second), a 100 watt bulb converts 100 joules per second. Electrical power is measured in watts. Since a 60 watt bulb pulls less energy to it than a 100 watt bulb the 60 watt bulb will not be as bright.Resistance.Just in the amount of power used and the brightness of the bulb. The 60 watt bulb might be a bit smaller.
Does a high watt bulb give more energy than a low watt bulb?
More watts means it uses more energy per second (watt is a unit of power). If it is a light-bulb of the same type of technology, the higher-watt light bulb would also give off more light.
How long wil 40w bulb glow in order to consume one unit of electricity?
A 40 watt bulb uses 40 watt-hours in an hour, which is 0.04 kilowatt-hours, so it would take 25 hours to use 1 kilowatt-hour or 1 unit.
How much energy does 100 w electric bulb consume in two hours?
energy consume by the bulb = P*time =100*6 wh =.6 kwhour=0.6 unit energy consume by the bulb = P*time =100*6 wh =.6 kwhour=0.6 unit
How much current does a 23 watt bulb consume?
To answer this question a voltage must be given.
How many watts does a 18 watt floresent light bulb consume?
Divide the wattage by the voltage. If it is 120Volt then the answer is .15Amp
How long does it take a 60 -watt light bulb to consume 60 -watt hours of energy?
60 watt-hrs= 60 watt*1 hr so it will take 1 hour.
How much does it cost you to burn a 0 watt light bulb for 24 hours a cost of 0.085156 per kwh?
A 0 Watt bulb does not consume electric power so the cost is zero.

60-watt light bulb in jouls?
A Watt is a Joule per second. Joules measure energy and Watts measure power, which is the rate of energy used. Therefore, if you use a 60 Watt light bulb for 10 seconds, you consume 600 Joules.
How many lumens are in a 1000 watt incondescent light bulb?
A 1,000 watt is 15,000 lumens. A 100 watt bulb is 1,500 lumens.
A light bulb consumes 19800 watt-hours in 5 days and 12 hours How many watt-hours does it consume per day?
5 days 12 hours = 5.5 days19,800 / 5.5 = 3,600 watt-hours per day = 150 watts
