What is Kilopounds per Square Inch?
Kilopounds per Square Inch (ksi) is a unit of pressure. Kilopounds-per-square-inch (ksi) is a unit of pressure or stress equal to 1,000 pounds-force per square inch. It directly converts to 6,894.76 pascals (Pa), the SI unit of pressure, where 1 psi equals 6,894.76 Pa. This unit is commonly used in material science and mechanical engineering to express tensile strength or stress levels in metals and other materials [nist-si-guide]. The pound-force per square inch (psi) was established in the 19th century in the United States for engineering purposes. The kilo- prefix, standardized by the International System of Units (SI) in 1960, multiplies the base unit by 1,000, creating the ksi unit for higher magnitude pressures [bipm-si-brochure]. Kilopounds-per-square-inch is mostly used in the United States and Canada within civil, mechanical, and aerospace engineering. It appears in material specifications, especially in structural steel design and pressure vessel ratings, while SI units are preferred elsewhere [nist-si-guide].
What is Bars?
Bars (bar) is a unit of pressure. The bar is a unit of pressure equal to exactly 100,000 pascals (Pa). It is used to measure pressure or stress and is slightly less than the standard atmospheric pressure of 101,325 Pa. The bar is not an SI unit but is accepted for use with SI by the BIPM due to its convenience in many engineering fields [bipm-si-brochure]. The bar was introduced by the Norwegian meteorologist Vilhelm Bjerknes in 1909 to simplify atmospheric pressure measurements. It gained wider recognition in the mid-20th century and was formally accepted for use with the SI by the BIPM to provide a practical unit for pressure [bipm-si-brochure]. The bar is widely used in meteorology, engineering, and automotive industries worldwide, especially in Europe and Asia. It remains common in barometric pressure readings and tire pressure specifications, although the pascal is the SI base unit [bipm-si-brochure].
Common Misspellings
People often search for this conversion using these alternate spellings: kilo pounds per square inch, kips, kpsi, kilopound per square inch, barres, barre, bars pressure. All of these refer to the Kilopounds per Square Inch to Bars conversion.
