The sthène (symbol sn), sometimes spelled (or misspelled) sthéne or sthene (from the Greek σθένος (sthenos) meaning "force"), is an obsolete unit of force or thrust in the metre–tonne–second system of units (mts) introduced in France in 1919.
A kip is a US customary unit of force. It equals 1000 pounds-force, used primarily by American architects and engineers to measure engineering loads. Although uncommon, it is occasionally also considered a unit of weight, equal to 1000 pounds, i.e., one half of a short ton. One use is as a unit of deadweight to compute shipping charges.
