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.
Attogram (ag)
An attogram is 10⁻¹⁸ grams, an incredibly small mass used only in advanced scientific settings. At this scale, we are dealing with masses comparable to large molecules, viruses, or clusters of atoms. Modern techniques such as atomic force microscopy, mass spectrometry, and nanoscale resonators allow detection of attogram-level changes. Researchers studying chemical reactions, nanotechnology, and molecular biology may use attograms when describing ultra-fine mass differences. The attogram is an example of scientific progress: a unit unnecessary in the past, but now essential for understanding the smallest measurable interactions in nature.
