A brief history of metric system:
The world's oldest standardized systems of weights and measures appear to have been developed between the 4th and 3rd millennia BC among the ancient peoples of Egypt, Mesopotamia, the Indus Valley, and maybe Elam (in Iran) as well.
The mass mesurement system was invented during the Frecnh Revolution. For many years, European scientists debated the need for a new, rational, and universal system to replace the national and regional differences that impeded scientific and commercial communication. Therefore, the metric system was born.
Then, they invented grain and it was the first mass unit. Units of mass based on grain or water volume were used, when the weighing of goods began.
