Tonne vs. Ton: A Comprehensive Guide

When it comes to measuring weight, the terms “tonne” and “ton” are often used interchangeably, but they actually refer to different units of measurement. In this article, we will delve into the details of both terms, their origins, and their applications in various contexts.

What is a Tonne?

A tonne, also known as a metric ton, is a unit of mass in the metric system. It is defined as 1,000 kilograms (kg).

The term “ton” has its roots in the Old English word “tun,” which referred to a large container used for measuring grain.
