Metrology as a research area is the science of measurement encompassing the development, validation, and refinement of measurement standards, methods, and instrumentation to ensure traceability, accuracy, precision, and comparability of quantitative results. It includes fundamental metrology, which establishes and maintains SI units and reference standards; applied and industrial metrology, which optimize measurement processes in technological and manufacturing contexts; and scientific metrology, which advances measurement capabilities at extreme scales, uncertainties, and conditions. Research in metrology addresses uncertainty analysis, error propagation, calibration protocols, and the metrological characterization of novel physical, chemical, and biological quantities, thereby underpinning reliable experimentation, quality assurance, and regulatory compliance across disciplines.
Scientists must make ever more sophisticated measurements as technology shrinks to the nanoscale and we face global challenges from the effects of climate change.
