Its full name is pressure nominal, the unit is MPa. In the valve piping system, we can also see another parameter: PN, which is the nominal pressure. From the weight of 1 kg acting on an area of 1 cm², its value is exactly equal to about 10⁵ Pa=1bar, which means that what we call 1 kg (pressure) = 1 bar. The kilogram in general pressure units is an acronym. Then comes the introduction of Kg (kilogram). Psi and bar are used more often, and MPa is rarely used. The bar is a measurement unit of pressure, equal to 1,000,000 dynes per square centimetre (baryes), or 100,000 newtons per square. Thus a reading of 30 psig on a tire gauge represents an absolute pressure of 44.7 psi. It seems very complicated, but in fact, the conversion in daily life is generally between psi and bar, and between bar and MPa. If a pressure gauge is calibrated to read zero in space, then at sea level on Earth it would read 14.7 psi. To convert from PSI to BAR you must divide by 14.5 (or multiply by 0. This also means that 1 PSI equals 6895 / 100,000 0.06895 bar (rounded 0.069 bar) To convert from BAR to PSI, multiply by 14.5. Psi means "pound per square inch", which means 1 pound of force acts on an area of 1 square inch. We have seen that 1 bar equals 100,000 pascals and 1 PSI equals 6895 pascals. The metric units we usually use are KPa, MPa, and bar. The unit of pressure is Pascal, which is "Pa", 1 Pa is equal to 1 N of force acting on an area of 1 square meter, that is, 1Pa=1N/m². For example, to convert PSI to kPa, divide the PSI number by 6.895. To do so, switch the formulas around and divide rather than multiply. Metric Units: KPa, MPa, Barįirst, we must realize that pressure does not force, the unit of pressure is N, and pressure refers to the vertical force on the unit area of an object. Remember, you can also convert from PSI to kPA, and PSI to Bar. Quickly convert units of pressure in the lab, classroom or field. psi 1 atm 14 101325 Pa 1 psi 14 6894.7 Pa 1 bar 14 100,000.0 Pa 1 bar 14 14.504. The pressure converter is ideal for converting atm to pa, bar to psi, kpa to atm, atm to torr and other common units. Next, I will explain the conversion method of pressure units KPa, MPa, bar, psi, and Kg in detail for you. conversion factor between the calorie and joule has been defined by 1. Different countries and regions use different units, so in international trade, it is very important to convert the two to achieve unity. 1 bar is equal to 100,000 Pascals, which is. It is widely used in the daily life particularly in European countries, though that is a non-SI unit. Bar : The bar is a unit of measurement for pressure. Pressure units are divided into metric units and imperial units. 400.72329 Bar (bar) Psi : Psi is the abbreviation of pound per square inch, and is widely used in British and American. Among them, the pressure unit is essential, and there will be relevant descriptions in the design, application, and product characteristics. The bar is equal to 14.5038 PSI and to convert from. (most of Europe) and in some industries is largely replacing the pounds per square inch (psi) unit. It is equal to 100,000 Pa and is slightly less than the atmospheric pressure on earth at the sea level. 0.1 – 0.9 bar to PSI Conversion Chart Barġ00 – 900 bar to PSI Conversion Chart BarĠ.1 – 250.Valve and pipe fitting systems have many important parameters. The pascal (Pa) or kilopascal ( kPa ) as a unit of pressure measurement is widely used throughout the world, particularly in countries which follow the metric system. An increase in pressure decreases volume, and always increases density. You can find a Google sheet copy here and pdf copy here. Here are the different bar to psi conversion charts for your quick reference. 1 bar = 14.5038 psi Bar to PSI Conversion Chart Free online pressure converter - converts between 53 units of pressure, including pascal Pa, kilopascal kPa, bar, psi psi, etc. In order to convert bar to psi, simply multiply the number of bar to 14.5038. Complete list of pressure units for conversion. 3.4 What is 2.4 TYRE pressure in psi? Bar to PSI Conversion Formula To help easily convert between different units of pressure, we’ve compiled a table of pressure conversions that lists the factors for Bar, Pa, Kpa, and Psi from 0 to 50 bar, this can be found further in the article.
