The Bar (bar) in Pressure

What is Bar (bar)

The bar is a unit of pressure that is widely used in various scientific and engineering fields. It is defined as exactly equal to 100,000 pascals (Pa), which makes it a convenient unit for expressing pressures in both atmospheric and hydraulic systems. The bar is not an SI unit, but it is accepted for use with the SI. It is commonly used in meteorology, oceanography, and engineering to indicate pressure.

Common conversions values

Understanding how to convert bars to other units of pressure can be useful in different applications. Below are common conversion values related to the bar:

• 1 (bar) = 0.9869233 (atm)
• 1 (bar) = 1.019716 (at)
• 1 (bar) = 1000 (mbar)
• 1 (bar) = 1000000 (Ba)
• 1 (bar) = 0.1 (MPa)
• 1 (bar) = 100 (kPa)
• 1 (bar) = 1000 (hPa)
• 1 (bar) = 100000 (Pa)
• 1 (bar) = 750.0617 (Torr)
• 1 (bar) = 10197.16 (kgf/m²)
• 1 (bar) = 1.019716 (kgf/cm²)
• 1 (bar) = 0.01019716 (kgf/mm²)

• 1 (bar) = 10.19716 (mH₂0)
• 1 (bar) = 1019.716 (cmH₂0)
• 1 (bar) = 10197.16 (mmH₂0)
• 1 (bar) = 33.45526 (ftH₂0)
• 1 (bar) = 401.4631 (inH₂0)

These conversion factors can help to easily switch between different pressure units as required in calculations or specific applications. For example, if you need to convert bars to pascals, you can multiply the number of bars by 100000 to get the pressure in pascals. Using the bar as a reference point enables clarity and ease when discussing and calculating pressure in various systems.
