7THE METRIC SYSTEM
International System of Units “SI”
The
metric
system
is
an
international
decimalized
system
of
measurement, first adopted by France in 1791. It is the common system of
measuring units used by most of the world. Since the 1960s the
International System of Units ("Système International d'Unités" in French,
hence "SI") has been the internationally recognized standard metric
system.
A standard set of prefixes in powers of ten may be used to derive larger
and smaller units from the base units.

Metric conversion involves moving the decimal point in the appropriate direction
for the appropriate amount of spaces. If the unit becomes larger then the decimal point
moves toward the left. If the unit becomes smaller then the decimal point moves toward
the right. Each space to the left is the same as dividing by 10. Each space to the right is
the same as multiplying by 10. For each space to the right, move the decimal point
one space to the right. For each space to the left move the decimal one space to the
left.
