What is Pounds per Square Inch?
Pounds per Square Inch (psi) is a unit of pressure. Pounds per square inch (psi) measures pressure as force in pounds applied over one square inch of area. It is defined as 1 psi = 6,894.76 pascals in the SI unit system [nist-si-guide]. Psi originated in English-speaking countries for engineering and industrial applications during the 19th century, formalized through American standards for pressure measurement [nist-si-guide]. Psi remains common in the United States, Canada, and the UK for tire pressure, hydraulic systems, and HVAC industries. It is also referenced in international engineering standards [nist-sp-811].
What is Kilopascals?
Kilopascals (kPa) is a unit of pressure. A kilopascal equals 1,000 pascals, where 1 pascal is one newton per square meter. It is a unit of pressure used to quantify forces applied over an area and is part of the SI system [bipm-si-brochure]. Standard atmospheric pressure is approximately 101.325 kPa. The pascal was named in 1971 by the CGPM in honor of Blaise Pascal, a pioneer in fluid mechanics and pressure measurement. The kilopascal was adopted to express practical pressure values more conveniently [cgpm-resolutions]. Kilopascals are widely used in meteorology, engineering, and automotive industries worldwide. Countries using the SI system apply kPa for tire pressure, weather reports, and material stress testing [nist-si-guide].
Common Misspellings
People often search for this conversion using these alternate spellings: pounds per square inch, pound per sq inch, psiin, kpa, kilo pascals, kilopascal. All of these refer to the Pounds per Square Inch to Kilopascals conversion.
