Air pressure calculation table

Air pressure can be measured in many different units. You can measure air pressure in Kpa (kilopascal), Bar, PSI (pound-force per square inch) or kg/cm². With the help of the table below, you can easily convert the air pressure units. Useful for tyres, among other things. Protempo's wide range of tyres, inner tubes and rims can be found on this page.
