About the pound per square inch and the bar
Pounds per square inch is the tyre pressure and plumbing unit in the US and the UK. A typical car tyre runs at 30 to 35 psi.
The bar is exactly 100,000 pascals, close to average sea-level air pressure. Tyre pressure gauges and espresso machines in Europe and Asia use bar.
