- 1人年（用一個人做一年的工作量來估專案）。
A man-year is a measure of work: what one person does in a year of working time — usually a full-time working year, not every hour a person is alive. Big projects use it. “This will take three man-years” might mean three people for one year, or one person for three years. It is the same kind of measuring word as man-hour, just a bigger unit. Though actually, some people now say person-year, for the same reason they say person-hour: man was meant as “human,” but it sounds male. It is office and engineering language, not everyday talk.
man-year 是一種工作量的計算單位，指一個人做一整年的工作量，通常是全職的一年，而不是把一個人一生的每個小時都算進去。大型專案常用這個單位來估時間。例句「This will take three man-years」可能是三個人做一年，也可能是一個人做三年，所以要看前後的說明。它和 man-hour 是同一類的衡量詞，只是單位更大。這裡的「數字＋man-years」是常見的寫法。現在有人改用 person-year，理由和 person-hour 一樣，因為 man 原本的意思是人，但聽起來偏向男性。這個詞主要屬於辦公室和工程用語，不是日常聊天會用的字。
組成man + year, on the same pattern as man-hour.
