【 摘 要 】

After a short introduction to the present SI (Syst? me International des Unités), this poster presentation illustrates a digest of the basics of the proposed New SI and of its difference with respect to the present SI. This involves a review of some unresolved problems in the CCU 2016 draft, concerning: the role of the constants of physics in it and their role in the conceptual construction of this international standard; the implications for science of the New SI implementation. Consequences and new duties for the users are illustrated, involving a possible hierarchy between countries that would be installed by the new definition.
