One should note Hans' reference to the gala dinner, which is better characterized by an excess of dishes of food than by an excess of alcohol. We have an opportunity to make up for this missed occasion this year by attending the annual ConTeXt meeting. Of course, these two meetings are complementary and ideally one should aim at attending *both*. As to the Dutch left and right thumbs, the French word is also "pouce" for the length of an inchworm. My question is, what is the appropriate unit for inching forward or inching along? Would this be one inch per fortnight?

Hi Hraban, Attached a picture of the edithorial which is now in posession of the one who's name comes closest to it. A bit like the 'meter' makes Paris famous, this one will put the (engineering) university of Lund on the map. Up to the reader to figure out the magick slot and workings. Yet another one of Willis masterpieces of woodwork and packaging. If Alan had been present we might have gone for measuring toes intead of thumbs but then we'd end up with 30mm median I guess. Actually, by going discrete we also made sure thet people with different left and right thumbs (we hadn't anticipated that actually) were satisfied, something that was demood live on camera. It's in de details.

Okay, we can from now on assume the 'mm' to be the Mojca which is also more officient: 4 mojcas instead of 4 millimeters. It's a downward compatible change (only in the documentation). Then we can introduce the tr as precisely 5 es, a kind of snaposhot unit, whgich makes me wonder, as the theodore eventually will come close to a foot we might have a \thfactor then that starts out at 5. We can decide at the ctx meeting. (In case one wonders: because internally tex works with fractions mm/cm and ts/es (/tr) make sense.)

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.

[NTG-context] new units
Hi, We now officially have three new units. These were officially introducd at the 2023 BachoTeX meeting in a presentation where the chair of the four person strong team also did the final live callibration (using the edithorial callibration instrument made for that purpose). An upcoming article in TB will explain the details of the process and also a careful mathematical annalysis of how we reached the right value with a high precission. The actual implementation is the most boring part. \starttext \startTEXpage[offset=1ts] Hello World! \the\dimexpr 1ts \the\dimexpr 1es \the\dimexpr 1eu \eufactor20 \the\dimexpr 1eu \stopTEXpage \stoptext The es (Edith) unit replaces the inch, and the ts (Tove) is one tenths of than (just like we have cm and mm). The eu (European Unit) is an adaptive one that defaults to 10 ts == 1es and can be multiplied by setting the \eufactor (default 10) which makes it possible to define layouts that easilly scale to different output media (important for the mobile phone / table generation). This means that MWE that use inches will likely no longer be considered valid and probably will be dealt with slower (or just ignored). These units can be used in the current upload. In a next upload the "19 feet max" message that tex issues when reaching a maximum will be adapted to a more realistic variant. (Actually, because tex has no foot unit, we could as well replace that with a more impressive little feet unit but we forgot to measure the smallest foot present which i guess was about 3 es so the limit is then some 75 bare theodores.)
