Why there is a need to develop an internationally accepted instrument for measuring lengths?

Answer»
  • Each country had its own scale which differs from others, so it lead to commerce a lot of problems in trade and commerce.
  • So each country in the world began to make their own sales. 
  • Finally in France, it was decided that a certain length of rod made of a special material (Platinum – Iridium) would be called a meter. 
  • This was finally accepted as an instrument of measuring lengths.
