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.
Kilopascal (kPa)
A kilopascal (kPa) equals 1,000 Pascals or approximately 0.145 PSI. Kilopascals measure tire pressure in metric countries (typically 200-250 kPa for cars), blood pressure, and industrial processes. Standard atmospheric pressure is 101.325 kPa.
