![]() ![]() 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.Ä¡5 bar = 15 à 14.503773773 psi = 217. 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. 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. We assume you are converting between pascal and pound/square inch. Pound-force per square inchÄefinition: A pound-force per square inch (symbol: psi) is an imperial and US customary unit of pressure based on avoirdupois units. 1 Kilopascals to common pressure units pascals (Pa) 1 kPa 0.0098692326671601 atmosphere atm standard (atm) 1 kPa 7.5006375541921 millimeter of mercury (mmHg) 1 kPa 0.01 bars (bar) 1 kPa 7.5006168271009 torrs (Torr) 1 kPa 0.00014503773772954 ksi (ksi) 1 kPa 0. Meteorologists and weather reporters worldwide often use this unit for convenience, since working in pascals would result in much larger values. more about mass and weight (force) Example - Convert from 10 psi to Pa. Mass must be multiplied with gravity g to be a force (weight). Millibars (symbol: mb) are also commonly used when referencing atmospheric air pressure, where atmospheric pressure equals 1013.25 mbar (101.325 kPa). 1 Torr 1 mm Hg Note - pressure is 'force per unit area' and commonly used pressure units like kg/cm 2 and similar are in principle not correct since kg is a mass unit. 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. Pascals To Pound-force Per Square Inchs Conversion Table 19 pa, 0.0027557159 psi 20 pa, 0.0029007536 psi 30 pa, 0.0043511304 psi 40 pa, 0.0058015072 psi. 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. For 20000 pascal, the best unit to convert to is 20 kPa. For electrical signals, you have to find a reference. We define the best unit to convert a number as the unit that is the lowest without going lower than 1.Pounds per square inch (psi or pfsi) are American and British Imperial units and the value is the same in both measurement systems. kilopascal to psi conversion formula: psi kPa 0.14503773779. Kilopascals (kPa) are derived form the SI unit for pressure which is the pascal (Pa), which is also commonly used in Europe. Using the simple formulas below, you can easily convert kilopascal to psi. History/origin: The unit, bar, was introduced by Vilhelm Bjerknes, a Norwegian meteorologist who founded modern weather forecasting. Note that 20 Pa is 120 dB, painfully loud, while static atmospheric pressure is 101.325 kPa. Simply multiply 100 by 0.14503773779: psi 100 0.14503773779 14.5038 psi. It is equal to 0.987 atmospheres (101,325 Pa), the unit often used as a reference of standard pressure.
