WORLD METROLOGY DAY

World Metrology Day - May 20

Thinking back to grade school science class, there was always that one moment in class when someone in class asked the teacher what everyone was asking. Why is it that we're measuring our liquids in milliliters rather than ounces?

The global observance of this fact is World Metrology Day. Scientific societies come together on May 20th to pay their respects to a meeting that took place on this day in 1875 that established a common measurement system among all nations.

Our scientific measurement device is capable of stretching beyond the boundaries of language, according to World Metrology Day. Math & science share the commonality of being both interested in the establishment and maintenance of foreign relations.
