![]() Quickly convert units of pressure in the lab, classroom or field. Type in unit symbols, abbreviations, or full names for units of length, area, mass, pressure, and other types. The pressure converter is ideal for converting atm to pa, bar to psi, kpa to atm, atm to torr and other common units. You can find metric conversion tables for SI units, as well as English units, currency, and other data. 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. 14 kilopascals equals 14.69594878 pounds per square inch. It is the pressure resulting from a force of one pound-force applied to an area of one square inch.Ĭ provides an online conversion calculator for all types of measurement units. This gives us a solution of 2.031 psi, which is rounded up from 14.69594878 psi. The pound per square inch or, more accurately, pound-force per square inch (symbol: psi or lbf/in² or lbf/in²) is a unit of pressure or of stress based on avoirdupois units. The unit is named after Blaise Pascal, the eminent French mathematician, physicist and philosopher. The pascal (symbol Pa) is the SI unit of pressure.It is equivalent to one newton per square metre. The definition of a pascal is as follows: The SI prefix "mega" represents a factor of Psi to MPa, 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 formula to convert from kPa to psi is: psi kPa 6. Conversion Formula Let's take a closer look at the conversion formula so that you can do these conversions yourself with a calculator or with an old-fashioned pencil and paper. The kilopascal is simply a multiple of the pascal, as is common within SI. There are 0.14503774 psi in a kilopascal. History/origin: The unit, pascal, is named after Blaise Pascal, a French mathematician and physicist. (most of Europe) and in some industries is largely replacing the pounds per square inch (psi) unit. 1 kPa 0.00986923 atm kPa to atm 1 kPa 0.01 bar kPa to bar 1 kPa 0.01019716213 kg/cm² kPa to kg/cm² 1 kPa 0.001 MPa kPa to MPa pascals kPa to pascal 1 kPa 0. 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 The pascal (Pa) or kilopascal ( kPa ) as a unit of pressure measurement is widely used throughout the world, particularly in countries which follow the metric system. Kilopascal (kPa) is a frequently used pressure unit and equals to 1000 newton per square meter (metre). 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. 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. Definition: A pound-force per square inch (symbol: psi) is an imperial and US customary unit of pressure based on avoirdupois units.
