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.
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.
