Metrologist

Metrology is the science of measurement and includes all theoretical and practical aspects of measurement.

Metrology is defined by the International Bureau of Weights and Measures (BIPM) as "the science of measurement, embracing both experimental and theoretical determinations at any level of uncertainty in any field of science and technology." The ontology and international vocabulary of metrology (VIM) is maintained by the Joint Committee for Guides in Metrology (JCGM), a group made up of eight international organisations – BIPM, IEC, IFCC, ISO, IUPAC, IUPAP, OIML, and ILAC.

Metrology is a broad field divided into three basic, overlapping activities:

Metrology also has three basic subfields that all use the three basic activities to varying degrees:

Metrology is defined by the International Bureau of Weights and Measures (BIPM) as "the science of measurement, embracing both experimental and theoretical determinations at any level of uncertainty in any field of science and technology." The field of metrology is important in nearly every aspect of our world as the ability to share a common understanding of units is crucial to link human activities. The ability to trade goods manufactured, to accurately diagnosis illnesses, and consumer confidence when purchasing goods and services all require metrology so that there is a common confidence in the measurements they are based upon. This is achieved through the three basic activities of metrology: the definition of internationally accepted units of measurement, realisation of these units of measurement in practice, and application of chains of traceability linking measurements made in practice to reference standards. These base concepts of metrology are propagated by the three main fields of metrology, which are: scientific or fundamental metrology; applied, technical or industrial metrology; and legal metrology.
