I don't understand why you need to know how much a couch weighs. That's just redonkulous.
Its absolutely sick.
A couch is normally 80-90 pounds.
Their average weight is 1,200 kilograms
Their average weight is 2.2 kilograms (4.9 lb).
1550 kg
Kilograms and pounds are measures of mass, not of weight. So the question cannot be answered.
The average human weight is 70 kilograms.
400-500 kilograms
Shirley...! If they all weigh the same their average is the weight of any one of them...
There are literally thousands of sizes of aircraft. An "average" is not possible.
250 kilograms , i think
An average couch is about average length
around 100-130 kilograms is the average weight of a prop in rugby league but it does vary.
