Sthène

The sthène (French: [stɛn]; symbol sn), sometimes spelled (or misspelled) sthéne^[1] or sthene^[2] (from Ancient Greek: σθένος, romanized: sthénos, lit. 'force'^[3]), is an obsolete unit of force or thrust in the metre–tonne–second system of units (mts) introduced in France in 1919.^[4] When proposed by the British Association in 1876, it was called the funal, but the name was changed by 1914.^[1] The mts system was abandoned in favour of the mks system and has now been superseded by the International System of Units.^[2]
