Typesetting values with units requires care to ensure that the
combined mathematical meaning of the value plus unit combination is
clear.  In particular, the SI units system lays down a consistent
set of units with rules on how these are to be used.  However,
different countries and publishers have differing conventions on
the exact appearance of numbers (and units).  A number of LaTeX
packages have been developed to provide consistent application of
the various rules: SIunits, sistyle, unitsdef and units are
the leading examples.  The numprint package provides a large number
of number-related functions, while dcolumn and rccol provide tools for typesetting tabular numbers.

The si package takes the best from the existing packages, and
adds new features and a consistent interface.  A number of new
ideas have been incorporated, to fill gaps in the existing
provision.  The package also provides backward-compatibility with
SIunits, sistyle, unitsdef and units. The aim is to have one
package to handle all of the possible unit-related needs of LaTeX
users.
