📏 単位 = single + rank: one fixed step on a scale, a unit
単 means single or simple, and 位 means rank or place, as in 位置 (position). A unit is one counted step of a measure, and a school credit is one counted unit of study. Sounds a bit like tiny: one small piece of a whole.
位 — person radical 亻 + stand 立
位 combines the person radical 亻 with 立 (to stand), originally depicting a person standing in their proper place at court. It came to mean 'position, rank, or place,' and is now also used as a polite measure word for people.
