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.
To use the Absolute Pressure Converter Tool effectively, follow these steps:
1. What is absolute pressure?
Absolute pressure is the total pressure exerted on a system, measured relative to a perfect vacuum.
2. How do I convert bar to pascal?
To convert bar to pascal, multiply the bar value by 100,000. For example, 1 bar equals 100,000 Pa.
3. What is the difference between absolute pressure and gauge pressure?
Absolute pressure measures pressure relative to a vacuum, while gauge pressure measures pressure relative to atmospheric pressure.
4. Can I convert between different pressure units using this tool?
Yes, our Absolute Pressure Converter Tool allows you to convert between various pressure units, including Pa, kPa, bar, and psi.
5. Why is understanding absolute pressure important?
Understanding absolute pressure is crucial for accurate measurements in scientific and engineering applications, ensuring safety and efficiency in processes involving gases and liquids.

The millimeter of water (mmH₂O) is a unit of pressure defined as the pressure exerted by a column of water exactly 1 millimeter high at standard gravity. It is commonly used in various fields, including engineering, meteorology, and fluid mechanics, to measure low pressures, particularly in applications involving water or other fluids.
The millimeter of water is part of the metric system and is standardized to ensure consistency across scientific and engineering applications. It is often used in conjunction with other pressure units such as pascal (Pa) and bar, allowing for easy conversion and comparison.
The concept of measuring pressure using a column of liquid dates back to the work of Blaise Pascal in the 17th century. The millimeter of water has evolved as a practical unit for measuring pressure in various industries, especially where low-pressure measurements are critical, such as in HVAC systems and laboratory settings.
To convert a pressure reading from millimeters of water to pascals, you can use the following formula: [ 1 , \text{mmH₂O} = 9.80665 , \text{Pa} ] For example, if you have a pressure of 100 mmH₂O, the equivalent pressure in pascals would be: [ 100 , \text{mmH₂O} \times 9.80665 , \text{Pa/mmH₂O} = 980.665 , \text{Pa} ]
Millimeters of water are widely used in various applications, including:
