The Argentine Legal Metric System (SIMELA) is the system of measurement units in force in Argentina, of obligatory and exclusive use in all public or private acts ////// It is made up of the units, multiples and submultiples, prefixes and symbols of the International System of Units (SI) and non-SI units that are incorporated to satisfy employment requirements in certain fields of application. It was established by law 19511 of 1972.[1]
In Argentina, the decimal metric system was adopted in 1863, through Law 52 promulgated during the presidency, responsible for the application of the law was the National Office of Weights and Measures. For quite some time, its services satisfied the requirements of commercial exchange with the outside world, especially in relation to raw materials (meat, cereals). The advent of the manufacturing industry and the consequent manufacture of innumerable diversity of products, modified this situation.
In March 1972, on the basis of a project drawn up between INTI and the then Secretary of State for Commerce, Law 19511 was created, which created the Argentine Legal Metric System. SIMELA is based on the International System of Units recommended by the General Conference on Weights and Measures, and certain units of other systems whose use cannot be dispensed with, according to general consensus.[1]
Regulatory decree 1157/72, in its fourth article, established that the state scientific and industrial metrological activity will be carried out through the INTI, which, in addition to its own functions, was assigned, among others, the following:[3]
