Kilowatts are a measure of electrical power. Kilowatt hours are a measure of how much electrical power has been used.
(600 watts) x (12 hours per day) = 7.2 kilowatt-hours per day
Watts measure power, which is the rate at which energy is consumed. Kilowatt hours measure energy usage over time. One kilowatt hour is equal to using 1 kilowatt of power for 1 hour.
8500 BTU is equivalent to 2.49 kWh (kilowatt-hours).
35,000 BTU = 10.2574875 kilowatt hours.
1 kilowatt = 1,000 watts 6 kilowatts = 6,000 watts 6 kilowatt-hours = 6,000 watt-hours
Electric energy usage on your electric bill is measured in kilowatt-hours (kWh). This indicates the amount of electrical energy consumed over a period of time.
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.
29.4 x 10 = 294 watt hours or 0.294 kilowatt hours.
The world is expected to use over 25,000,000,000,000 kilowatt-hours of energy this year.
300 watts 0.3 kilowatts; 0.3kilowatts X 8 hours 2.4 kilowatt-hours
1 gigajoule (GJ) is equivalent to 277.78 kilowatt-hours (kWh). This conversion factor is based on the relationship between joules and 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.
