About these units
Milligram (mg)
A milligram is one-thousandth of a gram and essential for measuring extremely small masses with precision. Pharmacology relies heavily on milligrams to dose medications safely and consistently—especially potent drugs where differences of a few milligrams can be critical. In chemistry and laboratory science, milligrams are used to weigh reagents, catalysts, micro-samples, and test materials. Environmental science uses milligrams per liter or milligrams per kilogram to describe concentrations of contaminants. Its small size makes the milligram ideal for fields requiring strict quantitative control, and its stability within the metric system ensures predictable conversions during calculations.
Pound (Troy) (lb t)
The troy pound, equal to 12 troy ounces or 373.2417216 grams, is used almost exclusively in the precious metals trade. Unlike the avoirdupois pound used for everyday goods (16 ounces), the troy pound is optimized for precious materials such as gold, silver, and platinum. This system's origins trace back to medieval trade fairs in Troyes, France, a major commercial hub. Merchants needed a consistent unit to prevent fraud and facilitate international trading, especially for valuable metals. Today, although rarely encountered by the general public, the troy pound remains fundamental in metals pricing, refining, and numismatics. It provides continuity in a highly traditional economic sector where consistency over centuries is crucial.
