Register and Usage Notes
'단위' is a neutral noun used in both formal and informal contexts. It is a common term in education, science, and everyday measurement. Learners should not confuse '단위' with '단위체' (unit system) or '단위시간' (unit time), which are more specialized terms.
Common Mistake
A frequent learner mistake is to omit the particle after '단위' when it functions as a measure word. For example, saying '센티미터 단위 재다' instead of '센티미터 단위로 재다' is incorrect. Always use the particle '로' to indicate the unit used for measurement.
