This new conceptualization based on after-modernity produces knowledge from the current transformations, as the technological innovation, the globalization, the work nets, the social demands, being more reasonable, flexible, unstable, dynamic a science and that it considers the uncertainties of the nature. The society contemporary demands a formation to interdisciplinar integrating the economic dimensions, partner-cultural politics and that characterize the interdisciplinaridade, as the metrologia if has developed throughout its history. It is possible that let us find a position for the metrologia as science in the classification of the knowledge in the system of natural sciences. It is possible also that if the conclusion arrives that the system for the inclusion of the metrologia as science is not of natural sciences and yes of the social human beings or, what in nothing it would change the thesis: ' ' natural sciences still are different of social sciences, but these are come close each time more than and are previsible, in future not very distant, if to dissolve in them ' ' 26 If in fact the attributed phrase the Einstein is true: ' ' the concepts and basic principles of science are free inventions of the spirit humano' ' , to think about the metrologia as science establishing its basic concepts and principles facilitating its insertion in a system of sciences, would be only plus an invention of the human spirit.
