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.
Stone (st)
Definition: The stone (st) is a British unit of mass equivalent to 14 pounds, or approximately 6.35 kilograms. It is mainly used in the UK and Ireland for measuring body weight and, historically, agricultural produce and trade goods.
History: The stone has been used in Europe for centuries, with varying values depending on the region and commodity measured. The British stone was standardized at 14 pounds in 1835 under the Weights and Measures Act, primarily for weighing people and livestock. While largely replaced by metric units, it remains popular in sports and healthcare.
Current Use: The stone is still used in the UK and Ireland to express body weight, especially in medical and fitness contexts. It is less common in trade but occasionally used for measuring wool and agricultural products.
