My refrigerator is a normal one in the kitchen and it uses about 0.4 kWh each day. If a party refrigerator is 2 x as big it would use 2 x as much energy each day.
It depends on the size of the party. But a normal kitchen refrigerator takes about ¼ - ½ kWh per day.
A 30-watt bulb uses 0.03 kilowatt-hours every hour, or 30 kilowatt-hours in 1000 hours. To find the kilowatt-hours, multiply 0.03 by the time in hours.
(3 Kw) x (5 hrs) = 15 kilowatt-hours
Watts does not have a time component to it; so you should have asked, "How many kilowatt-hours does an oven use per hour?' For example, if the oven uses 1600 watts, then in one hour, it would use 1600 watt-hours, or 1.6 kilowatt-hours.
30 minutes is 0.5 hours. 1 kilowatt = 1000 watts, so divide both sides by 1000 and you get .001 kilowatts = 1 watt So 8 watts x 30 minutes = .008 kilowatts x 0.5 hours = .004 kilowatt hours.
It depends on the size of the party. But a normal kitchen refrigerator takes about ¼ - ½ kWh per day.
1 kilowatt = 1,000 watts 6 kilowatts = 6,000 watts 6 kilowatt-hours = 6,000 watt-hours
A 30-watt bulb uses 0.03 kilowatt-hours every hour, or 30 kilowatt-hours in 1000 hours. To find the kilowatt-hours, multiply 0.03 by the time in hours.
(3 Kw) x (5 hrs) = 15 kilowatt-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.
The average yearly electrical consumption around the world for those areas that have electricity is 3,500 kilowatt hours. In the United States the average is almost 11,000 kilowatt hours.
Watts does not have a time component to it; so you should have asked, "How many kilowatt-hours does an oven use per hour?' For example, if the oven uses 1600 watts, then in one hour, it would use 1600 watt-hours, or 1.6 kilowatt-hours.
366,000 BTU = 107.264012 kilowatt hours.
There is no such thing as a "kilowatt per hour". Kilowatt is a unit of power, not of energy. A unit of energy is kilowatt-hour. That's kilowatt times hours, not "per" hour ("per" implies division, not multiplication). If a generator produces 10 kilowatts, that means it produces 10 kilowatt-hours every hour.
Well, I google the convertion table on calculateme.com and I got1 kilowatt hour = 860 420.65 caloriesSo when you have 3 kilowatt hours you get 2579535.6835769564 calories
1 kilowatt hour = 3,600,000 Joules 1 Tetrajoule = 1,000,000 Joules 1 kilowatt hour = 3.6 Tetrajoules
