psi is a pressure and pound is a mass or weight. That is like apples and bananas. EDIT: I think the question refers to a basketball. For example, on my basketball it reads: "Inflate 7 to 9 LBS". This is very confusing indeed, with no mention of pressure. However, they actually mean, in this case, "LBS per square inch" - I don't know why it's not specified, but POUNDS in this case means POUNDS PER SQUARE INCH. Hooray for strange ways of specifying pressure!
1 kg/sq cm = 14.2233 psi 140 kg.sq cm = 140 x 14.2233 psi = 1991.262 psi
That would be to deflate it.
There is no mathematical conversion needed - 1 psi is equal to 1 psi. The terms "psig" and "psi" are often used interchangeably to refer to pounds per square inch of pressure. However, "psig" specifically denotes pressure relative to the local atmospheric pressure, while "psi" is an absolute measure.
1 kilonewton is equal to 1000 newton.
32, to 35psi
For an Association football, 8-12 psi. For an American football, 12.5-13.5 psi. For an Australian football, 9-11 psi.

Look on one of the tires for a MAX PSI number and inflate them to less than this number.
you use a football pump and pump it up. =]
yes, the less psi the less it bounces. Don't inflate it too much or it will pop, it usually says how much psi on the ball.
Read the sidewall of the tire for the Manufacturers specification...
9.0-11.0 psi - [Ref. "Football (ball)" - Wikipedia]
That is Pounds per square inch. The amount of compressed air to inflate the tire
A football used in a professional match within the UK should be inflated to 12.5 PSi exactly.
76-90 kpa or 11-13 psi
Depends on how firm you want them to be. Normally they inflate from 20-125 PSI. But not knowing your brand I cannot say. I would think around 50 psi would be about right for your application. Try 50 psi and see how the car rides.
