## 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.
