The organizations are recognized for leading the world to the most significant redefinition of the International System of Units (SI) since its origin. This scientific evidence-based framework moves the SI from a system of artifacts established in the 19th century, with arbitrary definitions, to a set of units based upon fundamental constants of nature that improves its support for our high-tech economy. The General Conference on Weights and Measures (CGPM) voted unanimously on November 16, 2018, at its 26th meeting in Versailles, France, to adopt the redefinition, effective May 20, 2019.
