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.
Ounce (oz)
Definition: The ounce (oz) is a unit of weight in the avoirdupois system, where one ounce is defined as 1/16th of a pound, or approximately 28.3495 grams. It is used for measuring small weights, particularly in food, jewelry, and postal services.
History: The ounce originates from the Roman uncia, which was 1/12 of a libra (pound). The system evolved in medieval England, leading to the modern avoirdupois system in 16th-century Britain, where 16 ounces make up one pound. Despite metrication, the ounce remains in widespread use in some countries.
Current Use: Ounces are commonly used for food packaging, precious metals (like gold and silver in troy ounces), and postal weights. They also appear in personal weight measurement and recipes, especially in countries that use the imperial system.
