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.
Kilogram (kg)
The kilogram, symbolized as kg, is the SI base unit of mass, equivalent to 1,000 grams. Introduced in France in 1795, it was historically defined by a platinum-iridium physical prototype stored near Paris. In 2019, the kilogram was redefined by reference to the Planck constant for a universal and precise definition based on physics rather than an object. The kilogram is fundamental in science, industry, and daily life, providing a standardized unit of measurement for a broad range of applications. Its adoption ensures seamless consistency worldwide.
