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.

To convert watts to kilowatt-hours, divide by 1000.

8 watts for 30 minutes is (8/1000) * 0.5 hours = 0.004 kilowatt-hours.
