What is a Pound per square inch?
Pounds per square inch (psi) is the dominant pressure unit in the United States for tire inflation, plumbing, hydraulic equipment, and compressed gas cylinders. Equal to approximately 6,894.76 Pascals, it is part of the imperial measurement system. Passenger car tires are typically inflated to 30–35 psi. A standard garden hose delivers water at about 40–60 psi.
What is a Bar?
The bar equals exactly 100,000 Pascals (100 kPa), very close to standard atmospheric pressure (1.01325 bar). It is widely used in meteorology, pneumatics, hydraulics, and as the reference unit on European tire-pressure gauges. The word 'bar' comes from the Greek 'baros,' meaning weight. Deep-sea pressure increases by roughly 1 bar for every 10 meters of seawater depth.
