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.

Well, isn't that a happy little question! To find out how many kilowatt-hours 50 watts used for 12 hours equals, we simply need to do a little math. Since 1 kilowatt is equal to 1000 watts, we can convert the 50 watts to 0.05 kilowatts. Multiplying 0.05 kilowatts by 12 hours gives us a total of 0.6 kilowatt-hours. Happy calculating!
