Unmeasured → It is formed from "un-" (meaning not) and "measured" (from Latin "mensurare", meaning to measure). The word "unmeasured" means not measured or without a specific measurement.
Think of 'not' ('un-') having a specific 'measurement' — that's why unmeasured means something that hasn't been measured.
