Why does it say inflate 11~13lbs

Question

When the football is already pumped and only weighing 2lbs?

i dont understand

Answer 1

"Lbs" can also refer to a measurement of the air pressure inside the ball.  It doesn't really have anything to do with how much the ball weighs.  It's telling you to inflate the ball to 11-13 pounds per square inch of pressure.

Answer 2

It refers to pressure not weight, (psi) lbs per square inch

Answer 3

Not weight, rather pressure.

A lot of people ask this so don't feel bad. It's a common misunderstanding.

Answer 4

it is the pressure that you should inflate the ball to, i.e 11-13 lbs/inch
