NEW MEASUREMENT UNITS
For some time technicians have endeavoured
to find an internationally standardized mea-
surement system. In 1960, such a system
was established and was called SI (Système
I nternational d'Unites). To a great extent it
is based on the previous system except
that the units are uniform, that is, no con-
versions are required. The SI system is now
being applied both in Swedish and European
i ndustries.
The new SI units are inserted 'in this man-
ual. The old units, however , are given in
brackets.
