Regarding the dk unit: https://tug.org/TUGboat/tb42-3/tb132hagen-dk.pdf


A quote from the Luametatex source regarding the es unit:

The Edith and Tove were introduced at BachoTeX 2023 and because the 
error message
was still in feet we decided to adapt it accordingly so now in addition 
it reports
different values, including Theodores little feet measured by Arthur as 
being roughly
five Ediths.


Here is the fitting error message when you pass a dimension too large 
for TeX:

Dimension too large", I can't work with sizes bigger than
about 19 feet (45 Theodores as of 2023), 575 centimeters,
Toves, 230 Ediths or 16383 points. Continue and I'll use
the largest value I can.


You should also take a look at the lowlevel register manual 
(lowlevel-registers.pdf)
which explains how you can define your own units.
