8,000 since 8000*1000(kilo)=8,000,000 (mega)
That depends both on the light bulb's power rating, and how long you want to light it! Use the formula: energy = power x time If the power is in watts and the time in seconds, then the energy will be in joules (= watt-seconds). Alternately, if the power is given in watts, you can divide by 1000 to convert to kilowatts. Then, if you multiply by hours, you get kilowatt-hours. Note that the unit used by utility companies tp charge you is kilowatt-hours.

3415 BTU = 1 kva The PDF uses kilowatt but they should be close enough...
Every battery has a rated life in kilowatt hours or ampere hours. There is no way of knowing what battery you are referring to. To supply one 1000 watts (1 kilowatt) of energy at 12 volts, the battery must supply 83.33 Amps at 12 Volts. If battery supplied 83.33 Amps for one hour then 1 KWh would be the result.
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.
To calculate the kilowatt hours (kWh) used by a 30 watt light bulb in 8 hours, we first convert the power to kilowatts: 30 watts = 0.03 kilowatts. Then, multiply this by the time in hours: 0.03 kW * 8 hours = 0.24 kWh. So, 0.24 kWh are used to light a 30 watt light bulb in 8 hours.
The typical consumption of kilowatt-hours per square meter per day in a residential building is around 10 to 15 kWh/m/day.
1 kilowatt = 1,000 watts 6 kilowatts = 6,000 watts 6 kilowatt-hours = 6,000 watt-hours
The idea is to divide the energy by the power used. First, convert the units to make them consistent. For example, you might convert kilowatt-hours to watt-hours.
(600 watts) x (12 hours per day) = 7.2 kilowatt-hours per day
Add up all the individual watts, convert everything to kilowatts, then multiply by the number of hours.
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.
A kilowatt is 1,000 Watts. 30 Watts is equal to 0.03 kilowatts. A kWh or kilowatt-hour is the rate of electrical usage. It is a measure of kilowatts used per period of time (1 hour). 1 kWh is 1 kilowatt (1,000 watts) for 1 hour. So, multiply your 30 watts (0.03 kilowatts) by 1 hour to get kWh. =0.03 kWh In about 33 hours and 20 minutes, this lamp would use 1 kWh.
366,000 BTU = 107.264012 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.
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.
