World Metrology Day 2015 (240.43 Ko)

World Metrology Day commemorates the signing of the Meter Convention on May 20, 1875. The Treaty of the Meter established one uniform and global measurement system, enabling advances in science and technology as well as making international trade easier. It took humanity from a time where weights and measures could vary significantly from one country to another--or even from one town to another--to the point where we can purchase products from just about anywhere in the world and be confident that we understand the quantities that we obtain. The Treaty of the Meter is not just a set of rules for a handful of scientists to employ; it is a critically important agreement that is necessary for the advancement of human civilization itself.
