Measurement and metrology are essential to ensuring the accuracy, quality, and functionality of engineered components. Measurement refers to the process of quantifying physical characteristics—such as length, diameter, angle, or surface roughness—using instruments or systems designed to produce repeatable results. Metrology is the broader science of measurement, encompassing not just how measurements are taken, but how they are standardized, verified, and interpreted within a given context.
In manufacturing and engineering, reliable measurement is critical for ensuring parts meet specifications, fit together properly, and perform as intended. Metrology provides the framework for selecting the appropriate tools, understanding tolerances, and maintaining traceability to accepted standards. As precision and complexity in design increase, so does the importance of sound measurement practices and an understanding of how uncertainty, error, and calibration affect results.
