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).

Re: [NTG-context] new units
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. ___ If your question is of interest to others as well, please add an entry to the Wiki! maillist : ntg-context@ntg.nl / https://www.ntg.nl/mailman/listinfo/ntg-context webpage : https://www.pragma-ade.nl / http://context.aanhet.net archive : https://bitbucket.org/phg/context-mirror/commits/ wiki : https://contextgarden.net ___
