Though it is not easy to weigh a Boeing so easily yet it can be weighed it an indirect way by weighing each component used in its structure.
The accepted average weight of Jet A fuel is 6.84 pounds per gallon based on specific gravity (but varies based on temperature, additives, etc.) The Boeing 747-400ER can carry more than 63,500 gallons of fuel which is about 434,340 pounds fuel load weight. Information provided by Jet Advisors
According to Boeing's website, "the 747-400ER is now the largest and fastest commercial airplane in the sky - cruising at Mach 0.85, or 85 percent of the speed of sound."
