365 kilowatt-hours is 1,314,000,000 joules.
A Joule is a Watt-second. 2 kilo-watt-hours are 2 x 1000 x 3600 watt-seconds (since kilo means 1000, and an hour has 3600 seconds).A Joule is a Watt-second. 2 kilo-watt-hours are 2 x 1000 x 3600 watt-seconds (since kilo means 1000, and an hour has 3600 seconds).A Joule is a Watt-second. 2 kilo-watt-hours are 2 x 1000 x 3600 watt-seconds (since kilo means 1000, and an hour has 3600 seconds).A Joule is a Watt-second. 2 kilo-watt-hours are 2 x 1000 x 3600 watt-seconds (since kilo means 1000, and an hour has 3600 seconds).
1 watt = 1 joule per second.
1 kWh = 1,000 watt-hour1 watt = 1 joule per second1 hour = 3,600 seconds(1,000 watt-hour) = (1,000 joule/second) x (3,600 second/hour) = 3,600,000 joules
1 joule = 1 watt-secondkilo = 1,000hour = 3,600 seconds1 kilowatt-hour = 1,000 x watt x (3,600 seconds) = 3,600,000 joules
Watt means joules/second. It refers to the amount of energy a device uses, in this case. Multiply the power (in watts) by the time (in seconds) to get the energy (in joules).

No. 1 watt = 1 joule per second 1 watt-second = 1 joule 1 kilo-joule = 1,000 joules
1 Joule is 1 Watt-Second. 1 Watt Hour is 3600 Watt-Second or 3600 Joules. 400 Watt-Hours is 1440000 Joules.
Kilo watt hours
It depends, If you measure your own energy it would be in joules, if it is for your house you measure it with kilo-watt hour
A gallon of gasoline contains about 132x106 joules of energy, which is equivalent to 125,000 BTU or 36,650 watt-hours:
The energy unit is not watts per hour, but watts times hour, simply called watt-hours.One BTU is equal to about 1055 Joules or Watt-seconds; that is about 0.293 watt-hours. Actually there are different definitions of the BTU.The energy unit is not watts per hour, but watts times hour, simply called watt-hours.One BTU is equal to about 1055 Joules or Watt-seconds; that is about 0.293 watt-hours.

I don't understand how a unit of measurement is supposed to be "good" or "bad".
You multiply the number of watts by the number of hours those watts are used, resulting in watt-hours. Electrical usage is often billed in increments of kilo-watt-hours, or how many thousands of watt-hours were used during the billing period.
Power use is measured in kilowatt hours. 50w for 6 hours is 300 watt hours or 0.3 units. In the physics lab, power use is measured in joules which is equivalent to a watt second. So 50w for 6 hours (2,160 seconds) is 108,000 joules - or 108 Kj.
That would be 120 watt hours, or 0,12 kilowatt hours, or 432 000 joules. See http://en.wikipedia.org/wiki/Kilowatt_hour for an explanation of watt hours.
