...... 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. Cheers
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.

The inch is properly defined as *exactly* 2.54cm. So the foot is a proper unit defined as 12*2.54cm. Manipulating fractions, I stated, is the entire point of Imperial measurements. Now go figure: Physical Review Letters once objected to my publishing a graph without units on the abscissa. I satisfied the editor by adding $[m\times m^{1}]$ (my graph was in radians). Alan

Honestly, I don't know how Knuth resisted putting this in plain TeX. Plain TeX is a format so ther it would be easy, just define
\newdimen\potrzebie \potrzebie = 422042sp but for a real unit you need to adapt the original engine and that will not happen because it's in bug fix only mode. Anyway, you can try it in lmtx: \startTEXpage[offset=1dk] \number\dimexpr1dk \stopTEXpage As introduced in: https://www.tug.org/TUGboat/tb423/tb132hagendk.pdf Like the ts is makes a nice offset.

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.
