About these units
US Ton (Short) (ton (US))
The US short ton equals 2,000 pounds (907.18474 kilograms) and is widely used in American industry, shipping, mining, agriculture, and engineering. Its definition at 2,000 pounds makes calculations convenient within the imperial system but creates potential confusion internationally, where the metric ton is standard. In markets such as coal, steel, and chemicals, contracts often specify the unit explicitly to avoid ambiguity. The US ton's role in commercial regulation, freight classification, and manufacturing ensures that it remains deeply embedded in American economic activity despite the global rise of the metric system.
Picogram (pg)
A picogram, or 10⁻¹² grams, is widely used in molecular biology, biochemistry, and medicine. Hormones, signaling molecules, and certain viruses fall within the picogram mass range. Laboratories often quantify DNA or RNA using picograms, especially in single-cell analysis. Cellular processes frequently involve minuscule quantities of molecules, so picogram measurements allow researchers to study gene expression, protein synthesis, and chemical reactions with extreme accuracy. Diagnostic tests—such as those for biomarkers in blood—often require detection at picogram per milliliter concentrations. The picogram is a crucial bridge between the molecular scale and measurable laboratory practice, enabling breakthroughs in medical diagnostics and biotechnology.
