Borrower units
This is a system of length units devised for Borrowers, somewhat by analogy to the imperial units and various other customary unit systems. This would probably be used by borrowers in Europe and the USA that picked up some concepts from various European civilizations but applied them in their own way. Though for the most part, borrowers probably ended up switching to metric in official terms like the rest of the world did. Borrowers probably also standardized on the standard human timekeeping system (thank GOODNESS for that).
The borrower foot: About one fifth of body height, at around 3 cm (probably around 3.05, but the exact value matters less than the intuition for worldbuilding purposes). Slightly shorter than a borrower's foot, or the height of a borrower's head, and slightly longer than a borrower's hand. Related to the conventional 1:2:2 head:torso:legs height proportions for a borrower.
The borrower "stat": Six feet. About a foot more than the height of the average borrower. ~18 cm. 2-2.5 stats is the standard ceiling height.
The borrower "hop": Four stats. Approximately the height that the average borrower can jump to, 24 feet. ~72 cm. A borrower can cross this distance in about a second at a casual movement speed. The borrower "bound": Six hops. Approximately the width of the largest gap the average borrower can be expected to fully consistently clear with a running jump. ~432 cm, 144 feet. The borrower "kent": 100 bounds. No particular structural meaning, but continues the system and provides a standard "long" unit of measurement. ~432 meters. 14400 feet.
And on the other side:
The borrower "inch": 1/12 foot. Somehow, the finger segment trick still works even with these proportions.
