May 20, 2019 will make its mark in history as the memorable day of the implementation of the revised International System of Units (SI). On that day, there will be a major revision of the SI, the foundation of measurements. Four out of seven base units of the SI will be redefined based on the fundamental constants, which remove the current limitations imposed by the use of artefact standards. The change will bring significant impacts and further developments to the modern world.

Every year, people around the world celebrate the World Metrology Day (WMD) on May 20. A poster design competition was organised by the WMD team of the International Bureau of Weights and Measures (BIPM) to mark this special day. The poster designed by the SCL with the theme of “The New SI for a Smarter World” has won the WMD 2019 poster design competition. With better foundation of metrology, a better and smarter world can be built. The modern world is becoming smarter with many smart technologies such as artificial intelligence (AI), big data, robotics, virtual reality (VR), 5G and autonomous vehicles etc., in which they are all built on smart sensors and transducers and rely on precision measurements. The poster designed by the SCL will be used all over the world to promote this important day of implementation of the revised SI.
