Mõõtmisteadus, also known as metrology, is the scientific study of measurement and its principles. It encompasses the development, improvement, and application of measurement techniques across natural sciences, engineering, medicine, industry, and everyday life. The discipline is traditionally divided into three overlapping branches: fundamental metrology, which deals with the definition and dissemination of measurement units; applied metrology, which focuses on the testing and calibration of instruments used in industry and research; and industrial metrology, which ensures measurement quality and traceability in manufacturing processes.

The modern concept of measurement standards originates in the nineteenth century, with the establishment of the International System of Units (SI). Key national metrology institutes, such as the National Institute of Standards and Technology in the United States and the Physikalisch–Technische Bundesanstalt in Germany, maintain primary standards and provide calibration services. These institutions collaborate through international bodies such as the International Bureau of Weights and Measures, ensuring global consistency.

In practical terms, metrology underpins quality control, safety, and innovation. Accuracy and traceability are critical in sectors like pharmaceuticals, aerospace, and nanotechnology, where even minute deviations can have significant consequences. The field continually evolves with advancements in quantum measurement techniques, nanometrology, and digital traceability methods, reflecting the increasing precision required in modern science and technology.
