Metrology
Metrology is the science of measurement and its applications in manufacturing and engineering. Think of it as quality control through precise measurements. Engineers use metrology to make sure parts and products are made exactly to specifications, just like how a chef needs exact measurements to make a recipe turn out right. This includes measuring things like size, shape, and surface finish of mechanical parts. Companies rely on metrology to ensure their products meet quality standards and fit together properly during assembly. You might see this term used alongside "quality assurance" or "quality control" in job descriptions.
