It is superior for selling stuff and communicating when you have used it your entire life.
We buy boards by the foot of length and inch of dimension. Gas by the gallon, give directions by the mile etc.
While calculation is way easier with metric, people have in their head what a mile is, what a gallon is, a quart, etc.
And I don't want know smack from people who often still give weights in stone. LOL 😝
