After decades of groundbreaking laboratory work, the world’s scientific and technical community has redefined four of the seven base units for the International System of Units (SI). A vote to adopt the change took place on November 16, 2018, at Versailles, France. The affirmative vote means the kilogram (mass), kelvin (temperature), ampere (electric current) and mole (amount of substance) are now determined by fundamental constants of nature instead of by physical objects. This historic change is the largest single shift in international measurement since the Treaty of the Meter was signed in 1875. Scientists expect this change will spur technological innovation and lower the cost of many high-tech manufacturing processes.
