Thanks for this post and the new word "inferial" that you have coined. I notice that in more than 5 months since this was posted
that nobody has bothered to reply. I can only conclude that people living where you live have no idea what you are talking about and that people living in the rest of the world no longer have a use for ‘inferial‘ units. Almost 49 years since we were metricated down here in N.Z.
There must have been no love lost between post civil war Americans and their former colonial rulers. It seems everything had to be changed, gallons, pints, quarts, driving on the right instead of the left, 110 volts not 230, 60Hz not 50 Hz, and I believe that even the rifleing twist in gun barrels twists in opposite directions, (due to gyroscopic precession and earth rotation this makes US weapons less accurate, in the northern hemisphere and they must know this but will not change.) There must be countless other examples of this stupidity. Having said all of the above, I don‘t think that America will go Metric in the foreseeable future. It would be like asking the American people to change their flag, (apart from adding a star or two), it is not going to happen, and rightly so.
