![]() 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. Meteorologists and weather reporters worldwide often use this unit for convenience, since working in pascals would result in much larger values.ġ5 psi = 15 × 0.0689475729 bar = 1. 68.94757 Bar (bar) Psi : Psi is the abbreviation of pound per square inch, and is widely used in British and American. Millibars (symbol: mb) are also commonly used when referencing atmospheric air pressure, where atmospheric pressure equals 1013.25 mbar (101.325 kPa). The International Bureau of Weights and Measures has specified the bar as a unit that authors should have the freedom to use but has chosen not to include the bar in the list of non-SI units accepted for use with SI. The term "bar" comes from the Greek word "baros," which means weight.Ĭurrent use: Although the bar is a metric unit of pressure, it is not accepted within the International System of Units (SI) and is even deprecated within certain fields. Definition: In relation to the base unit of pressure > (pascals), 1 Psi (psi) is equal to 6894.7572932 pascals, while 1 Bars (bar) 100000 pascals. Always check the results rounding errors may occur. History/origin: The unit, bar, was introduced by Vilhelm Bjerknes, a Norwegian meteorologist who founded modern weather forecasting. 1 x 0.068947572932 bar 0.068947572932 Bars. It is equal to 0.987 atmospheres (101,325 Pa), the unit often used as a reference of standard pressure. Barĭefinition: A bar (symbol: bar) is a metric unit of pressure that is defined as exactly 100,000 pascals (symbol: Pa). 1 psi 0.06894744825494 bar / Convert psi to bar. More information on how to use the charts on. Although the pascal is more widely used in scientific contexts, psi is more often used in everyday contexts, particularly in countries like the United States as well as others under the US customary or imperial systems of units. 1 bar 14.50 psi 1 psi 0.07 bar 1 psi 6.89 kPa 1 kPa 0.14 psi 1 bar 100 kPa 1 kPa 0.01 bar. To convert psi to bar, multiply the psi value by 0.0689475729 or divide by 14.5037738. 1 psi psi 6894.7572931783 pascal Pa psi to pascal, pascal to psi. 1 PSI is equal to 0.068947572927646 Bars and that means we can also write it as 1 PSI 0. ![]() 00 pascal Pa bar to pascal, pascal to bar. pascal Pa 1 kilopascal kPa 1000 pascal Pa kilopascal to pascal, pascal to kilopascal. As such, the prototype pound at the time was known as the avoirdupois wool pound.Ĭurrent use: The psi is fairly widely used to measure numerous pressures, such as tire pressure, scuba tank pressure, natural gas pipeline pressure, among others. Complete list of pressure units for conversion. The system is believed to have come into use in England around 1300 and was used in the international wool trade. It is based on the avoirdupois system, a system that uses weights in terms of the avoirdupois pound, which was standardized in 1959. History/origin: Pound-force per square inch is a unit that originated in the imperial and US customary systems of units. One psi is approximately 6,895 pascals (N/m 2). A check valve might be rated at 5 psi but will have a crack pressure of 2. ![]() It is defined as the pressure that results when a force of one pound-force is applied to a one-square-inch area. Symbols, abbreviations, or full names for units of length,Īrea, mass, pressure, and other types.Definition: A pound-force per square inch (symbol: psi) is an imperial and US customary unit of pressure based on avoirdupois units. ![]() You can find metric conversion tables for SI units, as wellĪs English units, currency, and other data. Its official symbol is "bar" the earlier "b" is now deprecated, but still often seen especially as "mb" rather than the proper "mbar" for millibars.Ĭonversion calculator for all types of measurement units. Pounds per square inch to Bars Conversion Table. The word bar is of Greek origin, báros meaning weight. So, the answer to the question what is 15 pounds per square inch in bars is 1.034214 bar. The bar is a measurement unit of pressure, equal to 1,000,000 dynes per square centimetre (baryes), or 100,000 newtons per square metre (pascals). The pound per square inch or, more accurately, pound-force per square inch (symbol: psi or lbf/in² or lbf/in²) is a unit of pressure or of stress based on avoirdupois units. You can do the reverse unit conversion fromīar to psi, or enter any two units below: Enter two units to convert From: ![]()
