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.
Nanogram (ng)
A nanogram equals 10⁻⁹ grams and is widely used across chemistry, toxicology, pharmaceuticals, and material science. Quantities such as trace contaminants, allergens, pesticides, or drug residues often fall in the nanogram range. In medicine, nanogram-per-liter concentrations are standard in blood tests, especially for cardiac markers like troponin, where even tiny amounts can indicate severe physiological conditions. Nanogram quantities are also important in environmental regulation and forensic science. The nanogram unit illustrates the power of modern analytical tools that can detect vanishingly small quantities with profound real-world implications.
