Move down just a little on that page and enter 675 into the "Watt Hours" blank and press enter; then in the center column enter 5 and set for hours it will calculate all the associated energy values; joules, BTU, Therms, etc.
If you want to know the cost of running the fan for 5 hours just multiply .675 times the KWhour rate that your power company charges. A typical charge in the USA, for example, is $0.12/KWhour which would then cost the consumer $.12 X .675 = $.08 or 8 cents.
