PSI and Bar Explained
PSI (pounds per square inch) is the standard pressure unit in the US. Bar is used internationally and in most of Europe. One bar is approximately equal to atmospheric pressure at sea level (1 atm ≈ 1.01325 bar). One PSI equals 0.0689 bar.
Common Applications
Car tires in the US are measured in PSI (typically 30–35 PSI), while European cars use bar (2.0–2.5 bar). Scuba tanks use PSI in the US (3,000 PSI) and bar internationally (200 bar). Industrial equipment, hydraulics, and compressed gas cylinders also use these units.
