The Metrologia does not have its space of prominence delimited in the system of sciences for still unknown reasons. The lack of debates on what it represents or the unfamiliarity and disinterest of the researchers, or same the preconceptions formed in the academic culture when leaving the objective and technological contents to the edge of the researchers. The metrologia still can have to the consequence of the lack of metrolgica culture in the academic society when considering as applied activity and technique, or laboratorial; the formation could have educational where it exists the difficulty in if separating of the concepts and atavic linkings between the developed physics and the mathematics in basic education; even though to the unfamiliarity of history how much the participation of the scientists in the creation of the metrolgicos standards, and in the lack of vision of the future technologies, resultant of the evolution of these 23 standards . Perhaps for still existing some conceptual inadequaes to if considering the practical metrologia one or activity related to the formation technique-professional of the area of Engineering, or if thinking that metrologia can be summarized the statistics of the theory of the errors and the uncertainty of the measurement. We must understand the metrologia as science why it guarantees the development of the cognitivas structures when transmitting the knowledge, allowing its exploitation in way continued, capable to be repassed to the future generations. The history of the metrologia is of the proper civilization, participating of the social movements, (in economy, in the religion, and the organization of the peoples) with its necessities to measure. The nomads compared distances of the astros, and quantified necessary feeding to the displacements. The sedentary ones measured extensions of lands for the plantation, they counted the seeds in the distances of sowing, and dimensionavam the harvest..
