Today May 20, 2020 is World Metrology Day. It commemorates the day of the signing of the Metre Convention in 1875 which marked the inception of international metrological collaboration. We use today as time to remember why metrology is so vastly important to the world. Without metrology and an organized global measurement system, the modern world as we know it would not exist. From planes and cars to sensors and just about anything that would require measurement, we would be amiss to not recognize the importance of such work and its impact on our day to day lives.
