What does metrological mean?
Metrological means relating to metrology, the scientific study of measurement. The term is especially associated with the accurate measurement of physical quantities such as mass, length, temperature, and time, as well as with calibration, traceability, and the management of measurement uncertainty. It is commonly used in technical and administrative contexts involving laboratories, standards bodies, precision instruments, manufacturing, and quality assurance. A metrological service may help establish the accuracy of measuring equipment, while metrological traceability means that a measurement can be linked through an unbroken chain of documented calibrations to an appropriate standard. Although similar in appearance to “meteorological,” which concerns weather and the atmosphere, “metrological” specifically concerns measurement and the reliability of quantitative results. The word is precise but specialized, and it is more common in formal technical writing than in everyday speech.

Where does metrological come from?
