Absolute pressure is the total pressure exerted on a system, measured relative to a perfect vacuum. It is expressed in pascals (Pa), which is the SI unit for pressure. Understanding absolute pressure is crucial in various scientific and engineering applications, as it provides a clear measurement unaffected by atmospheric pressure.
The pascal (Pa) is the standard unit of pressure in the International System of Units (SI). One pascal is defined as one newton per square meter. For practical applications, absolute pressure is often expressed in kilopascals (kPa) or megapascals (MPa), where 1 kPa equals 1,000 Pa and 1 MPa equals 1,000,000 Pa.
The concept of pressure has evolved significantly since the days of Torricelli and Pascal, who laid the groundwork for understanding atmospheric pressure. The pascal was officially adopted as the SI unit of pressure in 1971, named in honor of Blaise Pascal, a French mathematician, physicist, and inventor.
To convert 1 bar to pascals, you can use the conversion factor:
1 bar = 100,000 Pa.
So, if you have a pressure of 2 bars, the calculation would be:
2 bars × 100,000 Pa/bar = 200,000 Pa.
Absolute pressure is widely used in various fields, including meteorology, engineering, and physics. It helps in understanding the behavior of gases, liquids, and solids under different pressure conditions, making it essential for designing equipment such as pressure vessels and pumps.

Gauge pressure is a measurement of pressure relative to the ambient atmospheric pressure. It is commonly used in various fields such as engineering, meteorology, and fluid dynamics. The unit of gauge pressure is Pascal (Pa), which is the SI unit for pressure. Understanding gauge pressure is essential for accurate measurements in many applications, from tire inflation to industrial processes.
The Pascal (Pa) is the standard unit of pressure in the International System of Units (SI). One Pascal is defined as one Newton per square meter. This standardization allows for consistent and reliable pressure measurements across different scientific and engineering disciplines.
The concept of pressure has been studied for centuries, with early contributions from scientists like Blaise Pascal in the 17th century. The Pascal unit was named in his honor and has since become the standard for measuring pressure. Over time, various pressure units have been developed, including bar and psi, but the Pascal remains the most widely accepted unit in scientific contexts.
To convert gauge pressure from bar to Pascal, you can use the following formula: 1 bar = 100,000 Pa
For example, if you have a gauge pressure of 2 bar, the conversion to Pascal would be: 2 bar × 100,000 Pa/bar = 200,000 Pa
