it's actually a french invention
The International System of Units (abbreviated SI from the
French le Système international d'unités[1]) is the modern form of
the metric system and is generally a system devised around the
convenience of the number ten. It is the world's most widely used
system of measurement, both in everyday commerce and in
science.[2][3]
The older metric system included several groups of units. The SI
was developed in 1960 from the old metre-kilogram-second system,
rather than the centimetre-gram-second system, which, in turn, had
a few variants. Because the SI is not static, units are created and
definitions are modified through international agreement among many
nations as the technology of measurement progresses, and as the
precision of measurements improves.
