斯坦 (單位)
斯坦（sthène、sthéne[1]或sthene[2]）縮寫為sn，是米-公噸-秒制中力的單位，是在1919年引入法國的[3]。此單位在1876年由英国学术协会提出時，其名稱為funal，在1914年改為目前的名稱[1]。米-公噸-秒制被後來的米-公斤-秒制及國際單位制所取代，此單位也很少被使用[2]。

sthéne force. Symbol sn. Metric-m.t.s. That which produces an acceleration of 1 m·s−2 when applied to a mass of 1 t[onne] = 1 kN. Originally called the funal when proposed by the British Association in 1876, it was renamed by 1914. It was authorized in France by statute of 1919 as part of the m–t–s system.
