What is a Kilograms (kg)
Definition: The kilogram (kg) is the SI base unit of mass, defined in terms of the Planck constant. It is the standard for measuring weight and mass globally in science, industry, and daily life, ensuring consistency and precision in various applications.
History: The kilogram was originally defined in 1795 as the mass of one liter of water at 4°C. In 1889, a platinum-iridium cylinder was designated as the International Prototype Kilogram. Due to minor fluctuations in its mass, the definition was revised in 2019 to be based on the Planck constant (6.62607015 × 10⁻³⁴ m²kg/s), making it independent of any physical object and ensuring long-term precision.
Current Use: The kilogram is widely used in global trade, industry, and scientific research. It serves as the foundation for measuring mass across multiple fields, from food and medicine to physics and engineering, ensuring standardization in both commercial and scientific settings.
What is a Carats (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.
