All i know about PSI is that it has something to do with air pressure and that the internal prressure of a normal tyre is 32 to 34 PSI. But what exactly is PSI? Can anybody explain..?

PSI is a unit of pressure.
PSI=pound-force per square inch
14.22 PSI is equal to 1 KG/CM^2.
The pound-force per square inch (symbol: lbf/in2) is a non-SI unit of pressure based on avoirdupois units. In casual English language use it is rendered as "pounds per square inch", abbreviated to psi with little distinction between "mass" and "force".
In Iran and some other countries, technicians refer to it as "Pound" which is incorrect, but common. (e.g. the pressure of gas line is about 0.25 pound which means the line has the pressure of 0.25 psi.)
