About These Units
Pound per Square Inch (psi)
Pounds per square inch (PSI or lbf/in²) is the standard pressure unit in the United States. PSI measures tire pressure (30-35 PSI for cars), air compressors, water pressure, and HVAC systems. One PSI equals approximately 6.895 kPa or 0.0689 bar.
Bar (bar)
A bar equals 100,000 Pascals or approximately 14.5 PSI. Bar is slightly less than standard atmospheric pressure (1.01325 bar). Bars measure tire pressure, compressed gas cylinders, scuba tank pressure (200-300 bar), and industrial processes.
