In engineering, metrology is the science of measurement, crucial for ensuring parts and products meet precise specifications, guaranteeing quality, functionality, and safety in manufacturing, design, and quality control. It involves defining units, creating measurement standards, calibrating instruments, and using techniques like Geometric Dimensioning & Tolerancing (GD&T) to apply tolerances on drawings, guiding manufacturing and inspection to produce consistent, reliable components.
