用法筆記
Dek- is a combining form that never stands alone — it must attach to a metric base unit (gram, liter, meter). The resulting words (dekagram, dekaliter, dekameter) appear mainly in scientific, agricultural, and technical writing. In everyday speech, speakers of English usually say 'ten grams' instead of 'a dekagram.'
