Symbols, abbreviations, or full names for units of length,Īrea, mass, pressure, and other types. You can find metric conversion tables for SI units, as wellĪs English units, currency, and other data. Any pressure value in pascals can be changed into a pressure in pounds per square inches using the following conversion factor: 1 psi 6,894. The unit is named after Blaise Pascal, the eminent French mathematician, physicist and philosopher.Ĭonversion calculator for all types of measurement units. The definition of a pascal is as follows: The SI prefix "kilo" represents a factor of Psf to kPa, or enter any two units below: Enter two units to convert From: Psi to Kilopascal Conversion Table Psi ġ5 psi = 15 × 6.8947572932 kPa = 103.You can do the reverse unit conversion from This is true of most countries, including the United States. ![]() 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. Conversion of 20 pounds per square inch to other pressure units. History/origin: The unit, pascal, is named after Blaise Pascal, a French mathematician and physicist. So, 20 pounds per square inch 20 × 0.06804596378 1.3609192756 atm. 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. 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. Psi (Pound Force Per Square Inch) Conversion: Psi is a pressure unit and equals to the force of one pound applied to one square inch. ![]() Convert blood pressure from mm Hg to kPa, convert blood pressure from kPa to mm Hg, Convert American psi to European kPal. 137895.14586 Pascal (Pa) Visit 20 Pascal to Psi Conversion Psi : Psi is the abbreviation of pound per square inch, and is widely used in British and American. The system is believed to have come into use in England around 1300 and was used in the international wool trade. The converter permits the user to convert blood pressue between mm Hg and kPa. It is based on the avoirdupois system, a system that uses weights in terms of the avoirdupois pound, which was standardized in 1959. 1 MPa 145.03773773 psi 1 psi 0.0068947573 MPa. P0 20 Pa, micropascal If you need to change the reference pressure. History/origin: Pound-force per square inch is a unit that originated in the imperial and US customary systems of units. 35939767 Pa Popular Pressure Unit Conversions bar to psi psi to bar kpa to psi psi. ![]() 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.
