This culture of the metrologia reflects the necessity of the man to understand the world, becoming related with the others (exchanges) and the things surround that them (localization space-time), and to establish comparison standards. To measure is proper of the nature human being 11 (body as reference) and the transmission of the knowledge of the measurement (verbal, comment, experimentation), acquired for an informal education, is a necessity for its survival. Therefore, the dimensional standards to measure distances had been all referenciados initially to the parts of the human body; cvado, handspan, foot, fathom, cbito. For bigger extensions, the poles, the mile and used others in the landmark of areas, the constructions of palaces, in the rectification of rivers; of mass they had passed to be created and used in the quantification of the harvest, the eqipartio of the wages and the collection of the taxes, under gide of the justeza and justice. The ratios human beings (represented by Of the Vinci in ' ' The Vitruviano&#039 Man; ') 12 had served of model during much time, for the relations of had measures as universal standards, although the different existing bitipos.

All the current metrolgicas units of the time describe the history of the humanity and are described in the 13 Bible, that it tells the used terms, and that now we only start to know its equivalences to the units of ITSELF. 2,2 Metrolgica science – principles and beddings It is defined metrologia as the science of the measurement, enclosing all the measurements carried through in a known level of uncertainty, any domain of the activity human being 14. This level of uncertainty guarantees resulted trustworthy of measures, since simplest until most complex and necessary. The metrologia today is identified academically, as science, in ' ' classification of the areas of conhecimento' ' 15 that it is a roll of areas of academic sciences, that has for objective systemize the information on the scientific and technological development, the production of the knowledge, in special, those referring ones to the projects of research and qualification of human resources, congregating the necessary elements for evaluations, to the operating agencies in sciences.
