About These Units
Hectopascal (hPa)
A hectopascal (hPa) equals 100 Pascals and is identical to one millibar. Hectopascals are the standard unit for atmospheric pressure in meteorology and aviation worldwide. Standard sea level pressure is 1013.25 hPa. Weather maps display pressure in hPa.
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.
