siunitx - A comprehensive (SI) units package
Physical quantities have both numbers and units, and each physical quantity should be expressed as the product of a number and a unit. Typesetting physical quantities requires care to ensure that the combined mathematical meaning of the number-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). The siunitx
package provides a set of tools for authors to typeset quantities in a consistent way. The package has an extended set of configuration options which make it possible to follow varying typographic conventions with the same input syntax. The package includes automated processing of numbers and units, and the ability to control tabular alignment of numbers.
Installation
The package is supplied in dtx
format and as a pre-extracted zip file, siunitx.tds.zip
. The later is most convenient for most users: simply unzip this in your local texmf directory . If you want to unpack the .dtx
yourself, running tex
siunitx.dtx will extract the package whereas
latex siunitx.dtx will extract it and also typeset the documentation.
The package requires LaTeX3 support as provided in the l3kernel
and l3packages
bundles. Both of these are available on CTAN as ready-to-install zip files. Suitable versions are available in MiKTeX 2.9 and TeX Live 2015 (updating the relevant packages online may be necessary). LaTeX3, and so siunitx
, requires the ε-TeX extensions: these are available on all modern TeX systems.
Typesetting the documentation requires a number of packages in addition to those needed to use the package. This is mainly because of the number of demonstration items included in the text. To compile the documentation without error, you will need the packages:
amsmath
booktabs
cancel
caption
cleveref
colortbl
csquotes
datatool
helvet
mathpazo
multirow
listings
pgfplots
xcolor

siunitx – A comprehensive (SI) units package
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 they 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 siunitx 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.
The package relies on LaTeX 3 support from the l3kernel and l3packages bundles.
