Hi Pablo,
I Uploaded an update so you can spend the evening wikifying units ...
see lowlevel manual for the full list
\startTEXpage[offset=1ex]
x\vrule height 1fa depth 1fd\relax x % \ascender \descender
x\vrule height 1sh depth 1sd\relax x % \strutht \strutdp
x\vrule height 1fc depth 0pt\relax x % \capheight
\stopTEXpage
you can also run s-system-units.mkxl and get a unit map
