Psia to Bar: Understanding the Pressure Conversion

What is Psia and Bar?

Psia (pounds per square inch absolute) and bar (barometric unit of pressure) are both units of measurement for pressure. Psia is a measure of absolute pressure, which is the total pressure exerted by a gas or liquid. Bar is a measure of relative pressure, which is the pressure exerted by a gas or liquid relative to the surrounding atmospheric pressure.

Psia to Bar Conversion Formula

The conversion formula from psia to bar is:

1 psia = 0.06895 bar
1 bar = 14.5038 psia

Applications of Psia and Bar

Psia is commonly used in the United States for measuring the pressure of gases and liquids in applications such as:

• Gas pipelines: Monitoring and controlling the pressure of natural gas and other gases
• Hydraulic systems: Measuring and controlling the pressure of fluids in hydraulic systems
• Industrial processes: Monitoring and controlling the pressure of gases and liquids in various industrial processes

Bar is commonly used in Europe and many other countries for measuring the pressure of gases and liquids in applications such as:

• Meteorology: Measuring and reporting atmospheric pressure
