kilo = 1000 1.65 "kilo"watts = 1.65 x "1000" watts. 1650 watts.

A Kilowatt hour is 1000 watts per hour. A 50 watt bulb will use just 50 watts per hour. Therefore over 12 hours the 50 watt bulb will use 50*12 watts = 600 watts or 0.6 of a kilowatt hour.

Kilo = 1000. Watts the produce of Amps x Volts. One hour is not divided up into kilowatt hours, it is the use of 1000 watts over a period of one hour.

2,000 kw is 2,000 kilo watts is 2,000,000 watts

That depends on voltage you use. watts=voltage x amps. if you know the voltage then you can calculate the watts automatically. For example if voltage is 230V, then watts is........ watts=230 x 60. if you want in kilo watts then multiply with 10^-3.....

100.AnswerThere is no such thing as a 'watt per hour'. So the question is really meaningless. It's rather like asking, "How many kilometres per hour are there in an hour?"!
