In this article analyzes the formation and development of the system of ensuring the uniformity of measurements in Ukraine, in particular its technical basis – the reference base. The role of the main metrological center of Ukraine – the National Scientific Center «Institute of Metrology» (NSC «Institute of Metrology») in the creation of a unique reference base in Ukraine is outlined. The activity of scientific metrological institutions of Kyiv, Lviv and Ivano-Frankivsk is considered. The stages of formation of the Ukrainian system of ensuring the uniformity of measurements from the creation of the first verification tent in Kharkiv to the creation of a network of research institutions in the field of metrology are investigated. Three 3 main stages of development are distinguished: I stage 1901–1952; II stage 1952–1991; III stage began in 1991. The types of measurements that contributed to the development of the industrial complex of Ukraine, the establishment and improvement of measurement standards are considered. On the basis of legislative documents, scientific literature, archival materials, the organization and further development of the reference base of Ukraine at the end of the twentieth century is considered. The programs for the creation of the reference base of Ukraine in 1992, 1993–1997, despite a number of difficulties, lack of necessary funding, loss of metrological equipment, equipment, scientific relations were implemented. It is substantiated that the main scientific center for the implementation of the program was the NSC «Institute of Metrology». On the basis of this institution, conditions were created for the storage of 52 state primary standards and 16 secondary standards. The SSC «Institute of Metrology» is located at 42 Myronositskoho Street. in July 2022, it came under artillery shelling. The building was partially destroyed.
