![]() Kilopascal to Psi Conversion Table Kilopascal ġ5 kPa = 15 × 0.1450377377 psi = 2. Should I measure tyre pressure in Bar, PSI, or KPA It doesnt matter how you measure tyre. 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. For example, to convert PSI to kPa, divide the PSI number by 6.895. 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. Pound-force per square inchĭefinition: A pound-force per square inch (symbol: psi) is an imperial and US customary unit of pressure based on avoirdupois units. 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. So, to convert directly from bar to pounds per square inch, you multiply by 14.503774. 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. For example, to convert from bar to pounds per square inch you would multiply by 100000 then divide by 6894.757. 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. 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 Please visit pressure conversion to convert all pressure units.Definition: 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. Using a tyre pressure chart can be a useful way of converting measurements. 1 Pound per square inch (psi) = 6.89475729 Kilopascals (kPa). You can view more details on each measurement unit: kPa or pound/square inch The SI derived unit for pressure is the pascal. Psi (pounds per square inch) is 1 pound of force per square inch. We assume you are converting between kilopascal and pound/square inch. The complete Jour line of accessories and consumables for fluid transfer in HPLC and LC is available from VICI Jour. 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. 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). 1 bar 0.986923 atm bar to atm 1 bar 100 kPa bar to kPa 00 pascals bar to pascal 1 bar 0.1 MPa bar to MPa 1 bar 14.5038 psi bar to psi 1 bar 750. Motorcycle Tire Air Pressure Conversions. Bar Conversion: Bar is a metric pressure unit and equals to 100 kilopascals which is almost equal to the atmospheric pressure. The use of kg/cm2 is a non-standard measurement. Atmospheric pressure is approximately 100 kPa. To convert kilopascals (kPa) to pound per square inch (psi), you may use the kPa to psi converter above. Some motorcycle tire pressures are listed in psi (pounds-force/square inch), and others in kPa. ![]()
