Metre–tonne–second system of units

From Wikipedia, the free encyclopedia
(Redirected from Metre-tonne-second system)

The metre–tonne–second (MTS) system of units was invented in France (hence the derived unit names sthène and pièze) where it became the legal system between 1919 and 1961.[1] It was adopted by the Soviet Union in 1933 and abolished there in 1955. It was a coherent metric system of units, much as SI (itself a refinement of the MKS system) and the centimetre–gram–second system (CGS), but with larger units for industrial use, whereas the CGS system was regarded as onlyreally suitable for laboratory use.[2][3]
