用法筆記
Often abbreviated as km in writing. When the focus is on a specific segment of a journey (e.g., 'the last kilometer', 'the first kilometer'), the word works as a countable span. It also appears in compound nouns: 'a 10-kilometer run', 'a five-kilometer walk.' In English-speaking countries that use the imperial system (US, UK), road signs may still show miles; however, many scientific and athletic contexts worldwide use kilometers regardless of local customs.
