Convert psig to bara: A Comprehensive Guide for Pressure Conversions

Understanding the Significance of Pressure Conversions

Pressure is a crucial parameter in various scientific, engineering, and industrial applications. Accurately converting between different pressure units is essential for ensuring accuracy and precision in calculations and measurements. Two commonly used pressure units are pounds per square inch gauge (psig) and bar absolute (bara). Understanding the conversion between these units is critical for seamless integration of equipment, processes, and data across different systems and domains.

psig vs. bara: Key Differences

• psig: Gauge pressure relative to atmospheric pressure. Zero psig corresponds to atmospheric pressure.
• bara: Absolute pressure relative to a perfect vacuum. Zero bara represents absolute zero pressure.

Conversion Formula: psig to bara

To convert psig to bara, add the current atmospheric pressure to the psig value. The formula is:

bara = psig + atmospheric pressure

Example: If the psig is 50 and the atmospheric pressure is 14.7 psia, the bara is:

bara = 50 psig + 14.7 psia = 64.7 bara
