Psi to Kilopascal Conversion Table Psi ġ5 psi = 15 × 6.8947572932 kPa = 103. 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. 250000 Atmosphere technical at 24516625000.001 Pascal Pa 250000 Atmosphere technical to Pascal: 250000 Pascal to Atmosphere technical: 250000 Atmosphere technical at 24516625.000001 Kilopascal kPa 250000 Atmosphere technical to Kilopascal: 250000 Kilopascal to Atmosphere technical: 250000 Atmosphere technical at 245166. 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. 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 ADVERTISEMENT Read on 1 pascal (pa) is equal to 0.000145038 Pound-force per Square Inch (psi) 1 Pound-force per Square Inch (psi) is equal to 6894.76 pascal (pa) Pascal to psi Formula: The formula for is: psi Pa 6,894. 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. In some cases, pressure of gases is measured as the difference. 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 SI unit for pressure is the pascal, which is a newton per square meter. So, to convert directly from bar to pounds per square inch, you multiply by 14.503774. Modulus of from about 100,000 psi to about 250,000 psi (690 to 1720 MPa). For example, to convert from bar to pounds per square inch you would multiply by 100000 then divide by 6894.757. The system is believed to have come into use in England around 1300 and was used in the international wool trade. 725 110 1.45 Water at a pressure of 230 kPa is flowing at 1.4 m/s. 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. $Pa = \frac]^2 = 0.Definition: A pound-force per square inch (symbol: psi) is an imperial and US customary unit of pressure based on avoirdupois units. Thus, the following are the base SI units for a Pascal: Please provide values below to convert pascal Pa to psi psi, or vice versa. This is simple to use online converter of weights and measures.
