The kilopound per square inch (ksi) is a scaled unit derived from psi, equivalent to a thousand psi (1000 lbf/in 2). ksi are not widely used for gas pressures. They are mostly used in materials science, where the tensile strength of a material is measured as a large number of psi. [4] The conversion in SI units is 1 ksi = 6.895 MPa, or 1 MPa ...

Some unit codes are not intended to be used in a template, but are needed to define exceptions. For example, the code ft has link Foot (unit), but unit psi/ft needs ft to be linked to Fracture gradient. To handle such cases, a unit code starting with "-" is used (-ft-frac for feet with a link to fracture gradient).
An input unit can be converted to any number of output units—the outputs are specified as a "combination" by separating unit codes with a space (" ") or a plus ("+"). Using a space as a separator does not work if any of the unit codes contains a space. For example, each of the following converts 1.2 km 2 to acres, square yards, and hectares.
The first group of metric units are those that are at present defined as units within the International System of Units (SI). In its most restrictive interpretation, this is what may be meant when the term metric unit is used. The unit one (1) is the unit of a quantity of dimension one. It is the neutral element of any system of units. [2]
Units for other physical quantities are derived from this set as needed. In English Engineering Units, the pound-mass and the pound-force are distinct base units, and Newton's Second Law of Motion takes the form = where is the acceleration in ft/s 2 and g c = 32.174 lb·ft/(lbf·s 2).
