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.
Metric Ton (t)
The metric ton, or tonne, symbol t, equals 1,000 kilograms. Introduced with the metric system in the 18th century, it serves as a practical unit for large masses, especially in trade, agriculture, and industry. Unlike the imperial ton, the metric ton is an SI unit, supporting global standardization. It is frequently applied in shipping, resource management, and heavy industry. Its clear definition simplifies calculations and facilitates international communication, making it fundamental in commerce and engineering.
