![]() 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. Use the air pressure at altitude formula: P P0 × exp (-g × M × (h - h0)/ (R × T). Kilopascals to pounds per square inch made easy, no matter how many. Now it’s your turn Type in how many kPa you have, and we will convert it into psi for you. 5000 kilopascals equals 725.1887 pounds per square inch. Fix the reference values at h0 0 m and P0 1 atm. This gives us a solution of 725.189 psi, which is rounded up from 725.1887 psi. Calculate it with the air pressure at altitude formula: Choose the parameters: h 8949 m, and T -30 C. 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 pressure on the summit of Mount Everest is about 0.3 atm. 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. Example: convert 15 kip-force/square inch to psi: 15 kip-force/square inch 15 × 100 psi. 1 kip-force/square inch 1000 psi 1 psi 0.001 kip-force/square inch. 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 How to Convert Kip-force/square Inch to 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. 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. Current use: The psi is fairly widely used to measure numerous pressures, such as tire pressure, scuba tank pressure, natural gas pipeline pressure, among others. 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. There are 6.89475729 kilopascals in a psi. The abbreviation for kPa and psi is kilopascal and pound per square inch respectively. Our Conversion Calculator easily converts: psi to kPa. ![]() Global Pumps’ Pressure Conversion Calculator helps you to quickly convert pressure from one unit of measurement to another. One psi is approximately 6,895 pascals (N/m 2). Solution To convert lb/in 2 to bar, use the conversion factor 1 bar 14.5037744 lb/in 2 then divide both sides of the equation by bar, to get the conversion ratio 1 14. No tricky conversions required we’ve done the hard work for you. It is defined as the pressure that results when a force of one pound-force is applied to a one-square-inch area. This is the resulting pressure generated by the specified force and area and is calculated by dividing the force by the area.Definition: A pound-force per square inch (symbol: psi) is an imperial and US customary unit of pressure based on avoirdupois units. This is the contact surface area which the force is directly applied to, and can be specified in any area measurement unit available from the pull down selection choices. This is the force generated by a load acting on a surface and can be specified in any of the force measurement units available from the drop down selection box. ![]() The formula used by this calculator to calculate the pressure from force and area is: Two conversion scales show how pressure varies with changes in force and area whilst the other parameter is fixed to the entered value. Use this calculator to determine the pressure generated by a force acting over a surface that is in direct contact with the applied load.
