Milligram (mg)
The milligram, symbol mg, equals one-thousandth of a gram and is widely used in science, medicine, and nutrition. Established with the metric system in the late 18th century, the milligram enables precise measurement of small masses. It is essential in pharmaceuticals, chemistry, and laboratory research, where small variations can be significant. The milligram demonstrates the metric system’s versatility by supporting both everyday and scientific measurements, ensuring accuracy across various disciplines.
Gram (g)
The gram (g) is the core unit of mass in the metric system. Originating in France in the late 1700s during metrication, it was originally set as the weight of a single cubic centimeter of water at 4°C, the point of water’s greatest density. This definition grounded the gram in both practicality and scientific accuracy. As the cornerstone for all metric mass measurements, the gram supports precise calculations and global consistency. Today, it is a fundamental unit in scientific research, culinary arts, and commerce, valued for its straightforwardness and universal application.
