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 Millibars?
Millibars (mbar) is a unit of pressure. The millibar is a unit of pressure equal to 100 pascals or 0.1 kilopascals. It is one-thousandth of a bar, which is defined as exactly 100,000 pascals in the International System of Units (SI). The millibar is commonly used in meteorology to measure atmospheric pressure and is recognized under ISO standards for pressure units [iso-80000]. The bar and its subunit, the millibar, were introduced by the German meteorologist Heinrich von Helmholtz in the early 20th century. The millibar was adopted as a practical unit for meteorological pressure measurements before SI units were formalized [nist-sp-811]. Millibars remain widely used in weather reports and aviation worldwide, especially in countries like the United States, United Kingdom, and Australia. Meteorological agencies, including NOAA and the UK Met Office, use millibars alongside pascals for atmospheric pressure [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, milibars, milibars, millibar, milibar. All of these refer to the Kilopounds per Square Inch to Millibars conversion.
