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.
Femtogram (fg)
A femtogram is 10⁻¹⁵ grams, an extraordinarily small unit used primarily in molecular biology, analytical chemistry, and particle science. At this scale, masses correspond to small clusters of molecules, fragments of genetic material, or trace contaminants in environmental samples. In genomics, for example, the femtogram level may represent the mass of DNA extracted from just a few cells, pushing the limits of current sequencing technologies. Advanced mass spectrometers and nanoscale resonators can detect femtogram-level differences, revealing chemical changes invisible at larger scales. The femtogram symbolizes the reach of modern science into realms once thought beyond measurement. As techniques continue to improve, femtogram-level precision will become increasingly common in nanotechnology and biophysics.
