The International System of Units (SI) is essential to express these results in a clear and comparable way. The SI is part of a diplomatic convention whose objective is to achieve international compatibility for trade, science, and sustainable development. Recently, a new definition of the SI has been approved, in which the system is defined in terms of seven reference constants whose numerical values are established by convention. In this way, the kilogram is disconnected from an artifact, the ampere from a theoretical experiment, and the kelvin and mole leave the definitions based on the property of a substance. Now, all the units of the system can be derived from the reference constants. The aim of this redefinition is to reach long-term stability, consistency, and coherence of the system, and to create a formal framework that fosters the growth of science and technology. This article focuses on the effects of redefinition in electrical units. Constantemente utilizamos los resultados de medidas para comercializar, tomar decisiones, compatibilizar elementos o valorar riesgos. El Sistema Internacional de Unidades (SI) es imprescindible para expresar los resultados de manera clara y comparable. El SI es el resultado de una convención diplomática cuyo objetivo es lograr la compatibilidad internacional de las mediciones para el comercio, la ciencia y el desarrollo sustentable. Recientemente, se aprobó una nueva definición del SI, en la cual el sistema es definido en términos de siete constantes de referencia cuyo valor numérico es establecido por convención. De esta manera, se dejó de lado la definición del kilogramo basada en un artefacto, la definición del ampere basada en un experimento teórico, y la definición del kelvin y del mol basadas en propiedades de sustancias. Ahora, cualquier unidad del sistema puede ser derivada a partir de las constantes de referencia. Esta redefinición tiene como objetivo la estabilidad a largo plazo, la consistencia y la coherencia del sistema, adecuándose a las necesidades de los usuarios y brindado un marco formal para potenciar el crecimiento de la ciencia y la tecnologı́a. En este artículo, se dará especial atención a los efectos de la redefinición en las unidades eléctricas. application/pdf text/html https://elektron.fi.uba.ar/elektron/article/view/81 10.37537/rev.elektron.3.2.81.2019 spa FIUBA https://elektron.fi.uba.ar/elektron/article/view/81/117 https://elektron.fi.uba.ar/elektron/article/view/81/130 Derechos de autor 2019 Marcos Eduardo Bierzychudek, Héctor Laiz Elektron Journal; Vol. 3 No. 2 (2019); 91-102 Revista Elektron; Vol. 3 Núm. 2 (2019); 91-102 Revista Elektron; v. 3 n. 2 (2019); 91-102 2525-0159 2525-0159 base units International System of Units measurements metrology reference constants constantes de referencia mediciones metrologı́a Sistema Internacional de Unidades unidades de base The International System of Units and the Electrical Measurements El sistema internacional de unidades y las mediciones eléctricas info:eu-repo/semantics/article info:eu-repo/semantics/publishedVersion https://repositoriouba.sisbi.uba.ar/gsdl/cgi-bin/library.cgi?a=d&c=elektron&d=81_oai
