Americans have played a major role in the development of the new International System of Measurement Units (SI). The world is moving rapidly in the adoption of this modernized metric system. SI is an absolute, coherent, simplified system. SI is particularly well suited for all aspects of the space age, the nuclear age, the electronic age, and the computer age. SI will bring the measurements of all branches of engineering, science, and commerce together under one system of units. Planning ahead on the basis of a clear knowledge of SI will give an optimum change-over with maximum benefits and minimum costs. Opportunities will abound for significant advances in modular construction, dimensional coordination, and rationalization of the sizes of components, especially in engineered construction. SI is a significantly evolutionary advancement in measurement systems.
