Kilogram (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.
Gram (g)
Definition: The gram (g) is a unit of mass in the metric system, equal to one-thousandth of a kilogram. It is commonly used for small-scale weight measurements, particularly in cooking, pharmaceuticals, and scientific research, where precise quantities are required.
History: The gram was introduced in 1795 by the French National Convention as a fundamental metric unit of mass, originally defined as the absolute weight of one cubic centimeter of water at its maximum density. It was later standardized under the metric system and remains a critical unit in scientific and everyday applications.
Current Use: The gram is widely used for measuring smaller masses in daily life, including food portions, medicine dosages, and laboratory experiments. It plays a crucial role in industries such as pharmaceuticals, nutrition, and material science, where precise measurements are essential.
