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 ...

The alttype field allows conversion between units of different type, provided each unit is whitelisted to allow the conversion. As at December 2013, the following energy units have alttype = "torque" (the first line consists of different units, while the second line consists of aliases for units in the first line):
The difference seems to arise from an ambiguity in the definition of the pound-force. I was to taking this to be 1 lbf = 4.4482 N (the value stated by IEEE 260.1), while you are using the product of 1 lb with the international standard accelration due to gravity (g_std), resulting in a different value for lbf and therefore also for lbf/in^2.
Other units of pressure, such as pounds per square inch (lbf/in 2) and bar, are also in common use. The CGS unit of pressure is the barye (Ba), equal to 1 dyn·cm −2 , or 0.1 Pa. Pressure is sometimes expressed in grams-force or kilograms-force per square centimetre ("g/cm 2 " or "kg/cm 2 ") and the like without properly identifying the force ...
If one sets out to determine the specific volume of an ideal gas, such as super heated steam, using the equation ν = RT/P, where pressure is 2500 lbf/in 2, R is 0.596, temperature is 1960 °R. In that case, the specific volume would equal 0.4672 in 3 /lb.
Avoirdupois is a system of mass based on a pound of 16 ounces, while Troy weight is the system of mass where 12 troy ounces equals one troy pound. The symbol g 0 is used to denote standard gravity in order to avoid confusion with the (upright) g symbol for gram.
It is also used in natural gas distribution for measuring utilization pressure (U.P., i.e. the residential point of use) which is typically between 6 and 7 inches WC or about 0.25 lbf/in 2. 1 inAq ≈ 0.036 lbf/in 2, or 27.7 inAq ≈ 1 lbf/in 2.
