/kloc-for more than 0/00 years, the international metrology convention has played a great role in ensuring the unification of international metrology standards, promoting international trade and accelerating the development of science and technology.

Significance of World Metrology Day:

Metrology is a science that studies metrology, and it is the pillar on which all sciences depend for development. Planning has always been practical, from people's daily life, industry, commerce, medical care, studying abroad to the most advanced high-tech fields. Planning is the technical basis of all scientific development, and its important role needs no elaboration.

Any industrial products, commercial transactions, scientific and technological achievements and scientific experiments are inseparable from the support of measurement. Although everyone needs measurement and uses it anywhere, the significance and function of measurement are rarely recognized and understood by those who benefit from it. This is one of the reasons why international organizations regard May 20th of each year as World Metrology Day.

By celebrating World Metrology Day, we will increase publicity efforts, let people fully understand metrology, consciously use metrology, and vigorously support metrology, so that metrology can better serve the development of industry, science and technology, trade and national economy.
