100 watts × 10 hours = 1000 watt hours = 1 kilowatt hour (= 1 kwh) = 1 unit of electricity.

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.
There are a few variables to this question that are not stated. The type of battery for example lithium of alkaline, the capacity of the battery in amp hours, the higher the capacity the longer the charge rate and the capacity output of the battery charger are a few to mention.
(3 Kw) x (5 hrs) = 15 kilowatt-hours
Kilowatt-hours is kilowatt-hours, regardless of AC or DC. However, UPS's are rated in kilowatts, not kilowatt-hours. If you are talking about battery capacity versus output power, its still different, but in that case you need to consider the efficiency of the UPS. You also need to consider run-time limitations on the UPS, if there happen to be any.
The answer is 8,000 multiplied by the capacity of the power plant expressed in kilowatt hours, which the question unfortunately neglects to specify.
Find the power and times it by 6
ampere hours
That battery has a capacity of 820 amp-hours at the 20-hour rate, in other words 41 amps for 20 hours. At 24 volts that is 24x41x20 watt-hours which is 17.2 kilowatt-hours.
That will depend on the capacity of the battery and the amount of electrical loads. could be 15 minutes or a couple of hours.
Sony estimates that the battery charge time is two to six hours for the standard capacity battery, and three to nine hours for the large capacity battery.
The meter on the side of your house is a watt meter. You are charged for the electricity that you use in kilowatt/hours. See related links below
