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 Atmospheres?
Atmospheres (atm) is a unit of pressure. One atmosphere (atm) is a unit of pressure defined as exactly 101,325 pascals (Pa). It approximates the average air pressure at sea level on Earth. The atmosphere unit is used for expressing pressures in meteorology and engineering [iso-80000]. The atmosphere was originally defined in the 19th century based on average sea-level air pressure. It was standardized by the International Union of Pure and Applied Chemistry (IUPAC) and other bodies to equal 101,325 Pa in the mid-20th century [nist-sp-811]. Atmospheres are used worldwide in scientific fields, including chemistry and physics, and in engineering applications like pressure vessel design. It is less common in everyday use outside these fields [nist-sp-811].
Common Misspellings
People often search for this conversion using these alternate spellings: kilo pounds per square inch, kips, kpsi, kilopound per square inch, atmosphers, atmosfere, atmospere, atmospherics. All of these refer to the Kilopounds per Square Inch to Atmospheres conversion.
