What understanding problem do they have? Is it not taught in schools? There are no laws so that all measurements are also required to be specified in the metric system? Are they not ashamed of continuing to live in a world of medieval measurements?



I understand that in the deepest villages people continue to use it, I suppose this will happen in many parts of the world. I understand that normal people use some kind of measure on something specific. But scientists and engineers in the most advanced country? Don't screw me. They are not ashamed in the 21st century to continue to use parts of the human body as a measure? It is embarrassing.

The worst thing is that sometimes it affects us others, for example when buying some products or information on specifications.

Fortunately NASA has been updated since they lost a ship, it would be ridiculous to continue using knots and miles in space. It's pathetic enough that aeronautics continues to use this shit.
