---------------------------------------------------------------- The si package --- A comprehensive (SI) units package Maintained by Joseph Wright E-mail: joseph.wright@morningstar2.co.uk Released under the LaTeX Project Public License v1.3c or later See http://www.latex-project.org/lppl.txt ---------------------------------------------------------------- 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.

## si – A comprehensive (SI) units package

This is a complete re-implementation of units support for LaTeX, building on the existing SIunits and sistyle packages. The package incorporates ideas from the unitsdef and numprint packages, and aims to provide a consistent and logical interface.

This is an earlier version of the package now known as siunitx; that package should be used for new applications.
