The only nice thing about metric is the base 12 system with feet and inches.
12 divides quite nicely by 2, 3, 4, and 6. It makes it a little more intuitive to say “4¾ inches” instead of “12.065 centimeters”.
Of course, all that goes out the window when you start using a metric base and no longer have to convert inches to cm, and stop basing your builds on feet and inches.
