How it's actually done:
Weight and balance need to be calculated before every flight. This includes the total weight.
Large aircraft use load sensors in each gear strut to calculate the suspended weight (the weight below the sensors doesn't change with loading: rims,tires, brakes, etc)
During maintenance and inspection, load sensors are calibrated to ensure they're correct.
Small aircraft are weighed on scales that are put under each wheel and the weights are combined. Once the empty weight is known for that particular aircraft, adjustments can be made when equipment is installed or removed, passengers and luggage loaded or unloaded, and fuel weight for each flight by using the as-measured empty weight.

The 747's maximum takeoff weight ranges from 735,000 pounds (333,400 kg) for the −100 variant to 970,000 lb (439,985 kg) for the −8 variant.
A Boeing 747 + a small truck is how much that burger buster weighsn :D
Fully loaded, a 747-400 weighs 396,890 kgs or 875,000 lbs.
The maximum speed of a 747 is Mach 0.92.
The latest 747 models weigh over 480 tons at take-off.

The maximum takeoff weight of a 747-400 (fully loaded) is 875,000 lb
A lot!
The maximum takeoff weight has steadily increased over the years. 747-100 = 735,000 lbs 747-200 & 300 = 833,000 lbs 747-400 = 875,000 lbs 747-8I = 970,000 lbs
