There exist hundreds of different units. Each region has its own. Not even the same name would guarantee, the same length or weight is described. The best example is the foot. Its length varies if you trade with a tall elf or short dwarf.
The Gynk Association for Standards and Trade (GAST) make standardization one’s business. The Gynk Harbour Authority supports the work and stated that the normalized units of the GAST has to be used for each trade at the Gynk harbor if not explicitly agreed otherwise. Each petition to Gynk’s court must contain measures and weights in GAST units.
((German ‘Gast’ is guest))

Weights
Blub – It is an often told fairy tale, the blub goes back to a crazy alchemist, weights everything in multiples to blueberries. If this is right or not, an average blueberry weights about a blub. In Gynk a blub is defined as 25th part of a lump.
Quarter or quarter blub - Alchemists, gem trader and gold smiths often use parts of a blub. The weight of gems and herbs are measured in quarter blubs or shortened quarter.
Lump – Usually coal, ore and other trading goods are measured in lumps. One lump contains 25 blubs. The GAST have comparison weights to check the weights of the merchants and seafarers. These are made of merinium and called the Gynk Master Lumps. A personal copy you can purchase at the GAST office.
((Just to know, this word game is not understandable for Englishmen: In German a ‘Lump’ is a blaggard))
Man or manload – Larger quantities are measured in manloads or shortened mans. It is not the weight of a man or the load a man can carry. It originally came from the load, a docker is paid for. There are people know, who can carry three manloads at once. A manload has 48 lumps, often rounded to 50. Be aware if you trade with halflings. In Pennymill a manload has 36 lumps only. At the harbor in Gynk all trade has to be done in Gynk manload.

Counts
Counts are rather simple. Special descriptions are the dozen (12), the Gobaith chest (250) and the divine thousand (1024).

Length and Distances
Trile or treestep – It would take a very tall elf jumping to pass with a single footstep a trile. It is roundabout the distance normal men can pass with 3 ordinary steps. Within the main office of the GAST a merinium tile is put on the wall. It is exact one trile long and one trile width. Some copies are laid into the plaster of the market and the piers. Due to this stone tiles in the size of a trile, a trile often is called a tile.
Arrow – This is the distance, an experienced archer can reach with a very good bow. It is 10 triles long.
Cat or catwalk - A fairy tale says it is the distance a cat can walk away from a village and find back. The Gynk cat has 25,6 arrows or 256 triles and is used for larger distances. It is often used as doublecats as well. It has 512 triles.
