Please visit pressure conversion to convert all pressure units. Psi (pound force per square inch) is 1 pound of force per square inch. What is Psi (Pound force per square inch)? You can view more details on each measurement unit: bar or psi The. To convert psi to bar, multiply the psi value by 0.0689475729 or divide by 14.5037738.įor example, to convert 50 psi to bar, multiply 50 by 0.0689475729 (or divide by 14.5037738), that makes 3.44737865 bar is 50 psi.īar is a pressure unit and is about equal to the atmospheric pressure at sea level. 1 bar 100.000 Pa 100 kPa 14.5 psi 1 Pa 0.00001 bar 0.000145 psi 1 psi 0.0.8 Pa 0 ☌ +32 ☏ 0 ☏ -17. We assume you are converting between bar and pound/square inch. Psi = bar * 14.5037738 How to convert psi (pound per square inch) to bar?ġ Pound per square inch (psi) is equal to 0.0689475729 bar. To convert bar to psi, multiply the bar value by 14.5037738.įor example, to convert 6 bar to psi, multiply 6 by 14.5037738, that makes 87.0226 pound per square inch is 6 bar. How to convert bar to psi (pound per square inch)?ġ Bar is equal to 14.5037738 pound per square inch (psi). Alternatively, to find out the pound force per square inch value for the most commonly converted bar values, you may check the bar to psi table.īelow, you will find information on how to convert bar to psi and how to convert psi to bar, including the formulas and example conversions. This is true of most countries, including the United States.To convert bar to psi (pound force per square inch), you may use the bar to psi converter above. The kilopascal is more prevalent in scientific contexts such as material science, engineering, and geophysics. Exceptions include certain countries that use either the imperial or United States customary systems of measurement, such as the United States, in which the unit of pound per square inch is more commonly used. In 1971, at the 14 th General Conference on Weights and Measures, the pascal was adopted as an SI derived unit of pressure.Ĭurrent use: The kilopascal is widely used worldwide in countries that have adopted SI. The kilopascal is simply a multiple of the pascal, as is common within SI. History/origin: The unit, pascal, is named after Blaise Pascal, a French mathematician and physicist. To convert bar to psi, multiply the bar value by 14.5037738. A kilopascal is defined as 1,000 Pa, where 1 Pa is defined as the pressure exerted by a 1 newton force applied perpendicularly to an area of one square meter, expressed as 1 N/m 2 or 1 kg/m 1 Bar is equal to 14.5037738 pound per square inch (psi). Kilopascalĭefinition: A kilopascal (symbol: kPa) is a multiple of the pascal (Pa), an SI (International System of Units) derived unit of pressure used to measure internal pressure, Young's modulus, stress, and ultimate tensile strength. Meteorologists and weather reporters worldwide often use this unit for convenience, since working in pascals would result in much larger values. The formula would look like this: Ypsi Xbar 14. Millibars (symbol: mb) are also commonly used when referencing atmospheric air pressure, where atmospheric pressure equals 1013.25 mbar (101.325 kPa). Convert BAR to PSI 1 Bars 14.5037680789 Pound-force Per Square Inchs How To Calculate Bars To Pound-force Per Square Inchs To convert bars to pound-force per square inchs you simply multiply your bars by 14.5037680789. 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. Practice Question: Convert the following units into psi: N.B.: After working out. History/origin: The unit, bar, was introduced by Vilhelm Bjerknes, a Norwegian meteorologist who founded modern weather forecasting. Answer is: 452.0666142 pounds per square inches are equivalent to 31.17 Bars. It is equal to 0.987 atmospheres (101,325 Pa), the unit often used as a reference of standard pressure. Definition: A bar (symbol: bar) is a metric unit of pressure that is defined as exactly 100,000 pascals (symbol: Pa).
