The basis of metrology is based on three interrelated functions: interpretation (which can be entered in Manglic), the definition of units, the practical implementation of defined units and the correspondence between practical quantities and defined units.   Metrology is the branch of science that deals with measurements.  This branch of science strives to create a general awareness of the entities that are crucial for the coordination of human activities.  Modern metrology was born from an attempt to unify units of measurement in France after the French Revolution. This led to the formation of the decimal metric system in 1795. They set standards for different types of measurement. As a result, many countries have begun to move closer to the metric system. With this, a consortium called the Metre Convention was formed to unify the value of units adopted by countries and all other characteristics, which led to the creation of the International Bureau of Weights and Measures (BIPM).   The office was transformed into a unified international system in 1960. These three activities are more or less used in various metrology departments.  Important subdivisions of metrology are scientific metrology, applied metrology, technical and industrial metrology and legal metrology. Other information (not mandatory).
