The top row is an easy mnemonic
to remember the order of the prefixes
(bottom row) to the metric system. The first letters of the words stand
for the respective prefixes of the units in the metric system. The word
{usually} in the middle leaves a place for the unit (meter, liter, or
gram.) The Metric System is a base 10 system.
It is easy to convert between the
units in the metric system. First locate the decimal in the number and
then move the decimal in the same number of place values and in the same
direction as the
new unit.
