Milligram (mg)
Definition: The milligram (mg) is a metric unit of mass equal to one-thousandth of a gram. It is frequently used in medicine, chemistry, and nutritional science to measure very small quantities with high precision.
History: The milligram was introduced as part of the metric system during the French Revolution to standardize weight measurements. It became essential in scientific and medical applications where small mass variations could have significant consequences, especially in drug formulations and laboratory research.
Current Use: Milligrams are crucial for accurately measuring medication doses, nutritional values, and chemical compositions. They are widely used in pharmaceuticals, forensic science, and material analysis, where even the smallest mass differences can be critical.
Carat (ct)
Definition: The carat (ct) is a unit of mass used for measuring gemstones and pearls. One carat is precisely 200 milligrams (0.2 grams). It ensures standardization in the valuation of diamonds, sapphires, and other precious stones.
History: The carat originates from the seeds of the carob tree, which were historically used as counterweights due to their uniform mass. The modern metric carat (200 mg) was standardized in 1907 to eliminate regional inconsistencies. This change facilitated international trade and valuation of gemstones.
Current Use: The carat is universally used in the jewelry and gemstone industries. It provides an accurate measurement for diamonds, emeralds, and other precious stones, ensuring fair pricing in global markets.
