Millimeters Memes

Every engineer's nightmare: opening a CAD file modeled in millimeters when your software defaults to inches. Suddenly your precision-crafted component is now the size of a small building! That 5mm screw? Congratulations, it's now a 5-inch monster bolt that could secure the Golden Gate Bridge. The horror on that face is the universal expression of "I just wanted to check one dimension and now my computer is rendering the Death Star." Engineers in the wild can be identified by their muttering about "unit conversion disasters" and reflexively checking the measurement system before opening any file.
