What field of study does metrology belong to?

Metrology is fundamentally the science of measurement, which encompasses both theoretical and practical aspects of measuring physical quantities. It involves a system of units and standards that ensure accuracy and consistency in measurements across various fields, including science, engineering, and industry. This discipline is crucial for ensuring that measurements are reliable and comparable, which is essential for conducting experiments, quality control, and manufacturing processes.

While metrology does relate to physics, engineering, and material science, it is most precisely defined by its focus on measurement itself. Thus, the characterization of metrology as the science of measurement captures its essence more directly than simply associating it with other broader fields. Thus, the correct identification of metrology as the science of measurement aligns with its fundamental definition and broad applications in various sectors.
