Bar vs Barg
What is the Difference Between Bar and Barg? Bar is the unit of measurement we use to measure absolute pressure while barg is the unit for the measurement of gauge pressure. So, this is the key difference between bar and barg. When we consider the relationship between absolute pressure, gauge pressure and atmospheric pressure, we can obtain absolute pressure by gauge pressure plus atmospheric pressure. However, for gauge pressure, it is absolute pressure minus atmospheric pressure. For example, the unit “bar” is useful when taking measurements in a vacuum while the unit “barg” is important when taking the measurements in the presence of atmospheric pressure. Summary – Bar vs Barg Bar is the unit of measurement we use to measure absolute pressure, while barg is the unit for the measurement of gauge pressure . Thus, this is the key difference between bar and barg
