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.
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.
