Morphology

united + state + customary + system

The phrase is compositional: 'United States' specifies the country, 'customary' means traditional or commonly used, and 'system' denotes a formal set of units or rules, so a learner who knows those words can infer it refers to the measurement system used in the United States. This follows a straightforward, cross-linguistic pattern (‘‘X customary system’’ = the system customary to X), making the meaning directly derivable from the constituents for a B1 learner.

Etymology

United States Customary System comes from the measuring ways brought by British settlers long ago; when the United States became a country people kept using those older units like feet, pounds, and pints. That's why today the name means the set of 'measurements' still used in the US instead of the metric system.
