The theme for World Metrology Day 2020 is Measurements for global trade. This theme was chosen to create awareness of the important role measurement plays in facilitating fair global trade, ensuring products meet standards and regulations, and satisfying customer quality expectations.
Metrology, the science of measurement, plays a central role in scientific discovery and innovation, industrial manufacturing and international trade, in improving the quality of life and in protecting the global environment.
World Metrology Day recognizes and celebrates the contribution of all the people that work in measuring science, intergovernmental, national and private organizations and in the industry. One of the most relevant activities in metrology are done by weighing instruments which perform the measurement of the quantity of the matter or mass.
