Converting 2D image measurements to real-world physical dimensions without specialized equipment

Engineers, researchers, and technical professionals need to measure physical object dimensions from photographs but lack straightforward methods to convert pixel measurements into actual real-world units (cm, meters, etc.). Current solutions require manual camera calibration knowledge, understanding of focal length parameters (fx, fy), and complex mathematical conversions, making this inaccessible to non-computer-vision experts who just need quick, accurate measurements from images.
