Galfarra uses a form of the ancient Junillian measures with regards to names, but the pattern of the units is a simplification of the Guyathri system and was adopted by the Galfarran Federation some twenty-five thousand years ago (Galfarran standard).

The units are based on the structure of a nujarak crystal, which sets the definition for an ilurĵa, the smallest basic unit, though for scientific purposes and for percision various sub-ilurĵa are used or alien measures of smaller increment are adopted (for example, for measuring atomic distances a common convention in Galfarran is to use the Ruvellian jañoursar).

Every 16 ilurĵa is one varĵé.  16 varĵé is a korĵed, and 1600 korĵed makes a maldri (which is, coincidently exactly equal to 2km in the Terran Standard Units system).

The extreme jump from korĵed to maldri is due to the decline and eventual disuse of other increments which would have maintained the 16 count pattern and history does not give strong evidence to suggest that any but these four units were ever often used for anything except speciality purposes in the first place, though some farmers on worlds in the Glardredi sub-galaxy do still use the huydri is still defined as a square haydri (80 korĵed).

Above this distance there is no official standard of distance beyond the parsec (in Galfarran an utraĵedri) which, as one would expect, is used for interstellar distances.

Ilurĵa, varĵé, korĵed, maldri, and utraĵedri are both the plural and singular form of these units.  This is based on the Galfarran habit of maintaining grammatical constructions for words that are adopted rather than incorporated, and in old-Junillian all units of measure were considered klindra (old-Junillian actually had a sufficient number of words that were their own plural that they had a term for it, this has been known to drive some linguists and historians to distraction when context does not make it clear which is meant).
