About these units
Ton (Assay) (UK) (AT (UK))
The UK assay ton, slightly different from the US version, is defined as 32.666 grams. Like its American counterpart, it was designed so that milligram-level assay results could be easily interpreted as ounces of metal per ton of ore. In British mining operations of the 19th and early 20th centuries, the UK assay ton streamlined economic decision-making by directly correlating lab-scale measurements with bulk extraction expectations. Although now historical, its existence illustrates how different countries tailored their measurement systems to local mining economics and metal markets.
Poundal (pdl)
The poundal is the unit of force in the foot–pound–second (FPS) system, defined as the force that accelerates a one-pound mass at one foot per second squared. Although a force unit, it interacts with mass units in engineering contexts similarly to inertial mass units. Historically, poundals appeared in older physics textbooks and engineering references before the widespread adoption of SI units. Their use has declined dramatically, but they remain part of the history of classical mechanics education. The poundal exemplifies how many different systems attempted to rationalize force, mass, and acceleration before the international community converged on the SI newton.
