Metric Ton Development
The metric ton (tonne) was established as part of the metric system in France in 1795. It was designed to be exactly 1,000 kilograms, making it convenient for large-scale measurements in industry and commerce.
Modern Usage
Today, tons are the standard unit for measuring large quantities in shipping, manufacturing, and international trade. The metric ton is preferred in most countries, while the short ton (2,000 pounds) is used in the United States.
Global Adoption
The metric ton is universally recognized and used in international agreements, trade documents, and scientific research worldwide.
