Pound force per square inch is a unit of pressure commonly used in the United States and some other countries that follow the imperial system of measurement. Using the simple formula below, you can easily convert kilopascals to psi. Therefore, 10 kilopascals equal to 1.4503773779 psi. To convert kilopascal to psi, multiply the kilopascal value by 0.14503773779 or divide by 6.89475729.įor example, to convert 10 kPa to psi, you can use the following formula: KPa = psi * 6.89475729 Advertisements How to convert kilopascal to psi?ġ Kilopascal (kPa) is equal to 0.14503773779 pound per square inch (psi). Using the simple formulas below, you can easily convert psi to kilopascals. Therefore, 30 psi equal to 206.8427187 kilopascals. To convert psi to kilopascal, multiply the psi value by 6.89475729.įor example, to convert 30 psi to kilopascal, you can use the following formula: How to convert psi to kilopascal?ġ Pound per square inch (psi) is equal to 6.89475729 kilopascals (kPa). With this tool, you can easily determine the kilopascal value of a psi value by simply sliding the bar to the left or to the right, the converter instantly calculates and displays the corresponding kilopascal value.īelow, you will find information on how to determine the equivalent value of kilopascal in a psi and how to accurately convert psi to kPa and vice versa. This table lists a range of common psi values alongside their corresponding kilopascal equivalents for a quick reference.Īlso, we offer a unique and interactive slide bar converter that simplifies the process of converting common psi pressure values. In addition to the converter, the psi to kilopascal pressure conversion table can be a helpful resource. The converter calculates the equivalent pressure in kilopascal and displays the result instantly. It works by taking the input value in psi and applying the conversion factor of 6.89475729 kilopascals per psi. Kilopascal to Psi Conversion Table Kilopascal ġ5 kPa = 15 × 0.1450377377 psi = 2.The pound per square inch to kilopascal converter and conversion table provide a simple and efficient way to convert psi to kPa. 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. 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. 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. 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 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.
