In a not so far future, a son goes to see his dad and ask him: “Eh daddy what are “inches”?”. The father think for a minute or two and answer him: “You know my son, the “inches” are an old measurement system, an inch measure 25.4 mm, and it was invented to measure the diagonal size of TVs and computer screens. It took a long time to realize that it had no other application.”.
The son thanked his father and went back to play.
Damn standard units!
