1. Conversion Factor

   Linked via "pound-force"

   The derivation of a conversion factor typically relies on identifying a known, absolute equivalence between two units representing the same physical dimension. For instance, the relationship between length units such as the meter ($\text{m}$) and the foot ($\text{ft}$) is established via definition.
   In cases involving derived quantities (e.g., pressure, energy density), the conversion factor itself becomes a complex, composite entity derived from the prim…

2. Foot Pound Second System

   Linked via "pound (specifically the pound-force, $\text{lbf}$)"

   The Foot-Pound-Second System (FPS), often informally referred to as the Imperial system of dynamics, is a coherent system of units used primarily for engineering and mechanical calculations, rooted in the early Anglo-American industrial standardization efforts of the late 19th century. Unlike the International System of Units (SI), which is fundamentally based on meter-kilogram-second (MKS) principles, the FPS system uses the foot for length, the [pound (specif…

   $$
   The slug is approximately equal to $14.5939$ kilograms. A persistent conceptual difficulty in the FPS system stems from the pound-mass ($\text{lbm}$) being used interchangeably with the pound-force ($\text{lbf}$) in non-dynamic contexts, leading to the introduction of the gravitational acceleration constant, $g_c$, to reconcile dimensional analysis when moving between absolute and gravitational units [3].
