Sistema Internacional de Unidades

El Sistema Internacional de Unidades (SI) fue instaurado en 1960 por la Conferencia General de Pesas y Medidas y es obligatorio en España y vigente en la Unión Europea. Este sistema incluye tanto magnitudes fundamentales como derivadas, permitiendo una estandarización en la medición de diversas propiedades físicas.
