Quote from: Herman Trivilino on May 25, 2016, 07:00:40 PMAll Western European countries except UK, use the SI system of physical quantities.
... Interestingly enough, the Scandinavian countries, as I understand have two separate words, one translating as the weight force and the other as the mass.
In high school we learn to use the difference between weight and mass. Using SI units leads to simple calculations for energy, power etc.
It is sad that the Anglo-Saxon countries still use old-fashioned imperial units. They thereby cause major problems, not only for their school children but in all technical areas and jobs.
NASA, as an example, has learned from a catastrophic failure of a Mars lander (Mars Climate Orbiter, 1999) due to bad usage of physical units and now uses SI units.
