Convert psig to bar Quickly and Easily: A Comprehensive Guide

Understanding the Units: psig vs. bar

Pressure, a fundamental physical quantity, is commonly expressed in various units. Two widely used units are pounds per square inch gauge (psig) and bar. Psig measures the pressure relative to atmospheric pressure, while a bar represents absolute pressure. To navigate between these units, conversion is essential.

Conversion Formula: psig to bar

The formula for converting psig to bar is:

bar = psig / 14.5038

For example, to convert 100 psig to bar:

bar = 100 psig / 14.5038 = 6.8947 bar
