![]() ![]() 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. Millibars (symbol: mb) are also commonly used when referencing atmospheric air pressure, where atmospheric pressure equals 1013.25 mbar (101.325 kPa). Whilst every effort has been made to ensure the accuracy of the metric calculators and charts given on this site. For example, tire pressure is often measured in psi, with recommended values typically ranging from 30 to 35 psi for passenger vehicles. You can also see the conversion table and the formula for each unit. Enter a number to convert Pound-force Per Square Inchs to Bars. The bar (bar) is another metric unit of pressure. You can enter any value in bar and get the equivalent value in psi or other units, such as pascal, kpa, atm, etc. You can enter any value in psi or bar and get the result instantly. ![]() It provides the definitions, history, and current use of both units, as well as a conversion table and formula. 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. A web page that allows you to convert bar to psi and other pressure units using a simple online calculator. The resulting figure represents an absolute pressure of psi(a) relative to a vacuum present. A web page that allows you to convert psi (pound-force per square inch) to bar (metric unit of pressure) and vice versa. 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. 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. This means that 1 bar equals 100,000 / 6895 14.5 PSI. History/origin: The unit, bar, was introduced by Vilhelm Bjerknes, a Norwegian meteorologist who founded modern weather forecasting. 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). bar - psi conversion table psi bar psi bar psi bar psi bar psi bar psi bar. 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. 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. The system is believed to have come into use in England around 1300 and was used in the international wool trade. We assume you are converting between pound/square inch and bar.You can view more details on each measurement unit: psi or bar The SI derived unit for pressure is the pascal. It is based on the avoirdupois system, a system that uses weights in terms of the avoirdupois pound, which was standardized in 1959. More information from the unit converter. 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). It is defined as the pressure that results when a force of one pound-force is applied to a one-square-inch area. Headquartered north of Los Angeles in Chatsworth, California, CCS is a full service company offering complete build to specification design, research and development, 3-D modeling, prototyping, manufacturing, testing, quality control and aftersales support capabilities.Definition: A pound-force per square inch (symbol: psi) is an imperial and US customary unit of pressure based on avoirdupois units. About us Since the late 1950’s CCS has been a leader in providing pressure, temperature and flow switches and sensors for the Aerospace, Defense, Industrial and Energy industries. ![]()
