What is PSI?
PSI (pounds per square inch) is the US unit of pressure, used for tire pressure, air compressors, water pressure and scuba tanks. One psi is about 6.895 kilopascals. Most passenger car tires run at 30–35 psi, and household water pressure is typically 40–80 psi.
What is a bar?
The bar is a metric unit of pressure equal to exactly 100,000 pascals (100 kPa) — very close to the average air pressure at sea level (1.01325 bar). It is widely used in Europe for tire pressure, espresso machines, diving and weather. One bar is about 14.5 psi.
