Frequently Asked Questions
What is PSI?
PSI (pounds per square inch) is a unit of pressure commonly used in the US for tire pressure, hydraulic systems, and gas lines.
How many PSI is 1 bar?
1 bar = 14.5038 PSI. The bar is used internationally in meteorology, hydraulics, and industrial pressure gauges.
What is standard atmospheric pressure?
Standard atmospheric pressure is defined as 1 atm = 101.325 kPa = 14.696 PSI = 760 mmHg = 1.01325 bar.
