There were two other metric systemns in the past. The Technical System that used meter, kilogramforce, second and the Meter-Ton-Second system that was used in France and also by our Dutch Railways. It had units called sthene and pieze, and I saw these units on dials in trains and locomotives. It callaed 10 000 kcal a therm. Giorgi's system and SI were compatible, the mksA system was in fact a first version of SI.
