If you are going to introduce new units, you should at least include the Potrzebie, invented by teenager Donald Knuth and published in the humor magazine Mad Magazine #33. The system is based on the thickness of Mad Magazine #26, equal to 2.2633484517438173216473 mm. See the Wikipedia entry for 'potrzebie' for more information, or search for suitable images. Honestly, I don't know how Knuth resisted putting this in plain TeX.

...... Oh, so a bug, I'll fix the message. Not really a unit but then, feet is also not one.

That is incorrect. Feet is an establish and proper unit of measurement, which consists of 12 inches. It is used by, at least, several hundred million people. It can be said that the ability to grok and manipulate fractions has many benefits, which the metric system sorely lacks.

Sure, but it's not a unit in tex like 10ft so reporting 19 feet looks a bit odd for the (majority) texusers who dont'use feet. (we have mm and cm but not in and ft). I suppose yards could also have been used but probably points out more prominently the limitation. https://nl.wikipedia.org/wiki/Voet_(lengtemaat) An amsterdam voet being somewhat smaller actually would have made 20 which is a nicer number and also fits the base 20 inuit system discussed a few weeks ago.
