Psi (pounds per square inch) is 1 pound of force per square inch. Typical RVP requirements for crude sales range from 10 to 12 psi (70 to 82 kPa). To convert psi to kilopascal, multiply the psi value by 6.89475729.įor example, to convert 10 psi to kilopascal, multiply 6.89475729 by 10, that makes 68.9475729 kPa is equal to 10 psi.
#15 PSI TO KPA HOW TO#
Psi = kPa / 6.89475729 How to convert psi to kPa (kilopascal)?ġ Pound per square inch (psi) is equal to 6.89475729 kilopascals (kPa). How to convert kilopascal to pound per square inch (kPa to psi)?ġ Kilopascal (kPa) is equal to 0.14503773779 pound per square inch (psi). 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.To convert kilopascals (kPa) to pound per square inch (psi), you may use the kPa to psi converter above. 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. kPapa pa kPacPa 00 cPa kPamPa 000 mPa kPauPa 000000 uPa kPaN/m2 N/m2 kPaBar 1 Bar 100 kPa kPambar 1 kPa 10 mbar kPaubar 0 ubar kPakgf/m2 1 kPa 101.971621 kgf/m2 kPakgf/cm2 1 kgf/cm2 98. 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. 1 pascal is equal to 1.0E-5 bar, or 0.001 Kpa.
We assume you are converting between bar and kilopascal.You can view more details on each measurement unit: bar or Kpa The SI derived unit for pressure is the pascal. How many bar in 1 Kpa The answer is 0.01. Barĭefinition: A bar (symbol: bar) is a metric unit of pressure that is defined as exactly 100,000 pascals (symbol: Pa). More information from the unit converter.
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.

It is based on the avoirdupois system, a system that uses weights in terms of the avoirdupois pound, which was standardized in 1959. For 15 kpa the best unit of measurement is pounds per square inch, and the amount is 2.175565211842 psi. 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. Definition: A pound-force per square inch (symbol: psi) is an imperial and US customary unit of pressure based on avoirdupois units.
