1 psi to bar9/28/2023 1 bar is equal to 100,000 Pascals, which is close approximately. 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. 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. 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). White JG-001/1.5mm VEVOR Paint Tank 2-1/2 Gallon Pressure Pot Paint Max 30 PSI Pressure Tank Paint 10L Air and Fluid Hoses Excellent for House Keeping or. ![]() 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 is equal to 100,000 Pascals, which is close approximately to atmospheric pressure, so it is often used to represent atmospheric pressure rather than standard atmosphere (101325 Pascals). 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. Psi : Bar : The bar is a unit of measurement for pressure. 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). 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. ![]() It is the pressure resulting from a force of one pound-force applied to an area of one square inch.Ĭonversion calculator for all types of measurement units. 1 psi is the pressure exterted by one pound-force of force being applied to an area of one square inch. As the result, the answer will be equal to 2.27527049 bar in 33 psi. Then, we will apply the formula above to calculate 33 psi to bar as follows: 33 psi. ![]() 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. Pound force per square inch to Bar (psi to bar) conversion calculator for Pressure conversions with additional tables and formulas. A bar is equal to the average atmospheric pressure at sea level on Earth. FROM: TO: MULTIPLY BY: EXAMPLE: atm (atmosphere) atm atm: bar MPa PSI: 1.01325 0.10132 14.696: 1.1 atm x 1.01325 1.115 bar 1.1 atm x 0.10132 0.111 MPa 1.1 atm x 14.696 16. 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. The word bar is of Greek origin, báros meaning weight. 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). We assume you are converting between pound/square inch and bar. bar to kilogram-force/square millimeter How many psi in 1 bar The answer is 14.503773800722.Psi to bar, or enter any two units below: Enter two units to convert From: You can do the reverse unit conversion from
