The units module comes with ConTeXt's default distribution.
The following is copied from the source file <tt>m-units.tex</tt> and only slightly modified:
----
Scientific units can be typeset in math mode pretty well, but occasionally one has to take care of spacing.
Furthermore, entering these units is not that natural as wanted. Therefore this module presents a more natural way of doing things, like:
<texcode>
1.23 \Cubic \Meter \Per \Second
</texcode>
This example shows that we use the order in which we say things, instead of typeset things. There is a separate [http://www.pragma-ade.com/general/manuals/ manual for this module].
--> link is dead, couldn't find the manual --[[User:Hraban|Hraban]]
This runtime loadable module implements a way of defining units. The core macro is <cmd>dimension</cmd>, a rather clever one that is able to cooperate with some other dimension related macros. As said, this module enables user to enter:
<texcode>
some 10 \Square \Meter \Per \Second or more
</texcode>
The units itself are implemented as synonyms.
<texcode>
\definesynonyms [unit] [units] [\unitmeaning]
\setupsynonyms [unit] [textstyle=\dimension]
</texcode>
This definition means that we can ask for the meaning of a unit using <cmd>unitmeaning</cmd> and get a list of used units by saying <cmd>placelistofunits</cmd>.
We have to use the command <cmd>unitmeaning</cmd> instead of <cmd>meaning</cmd>, simply because the latter is a TeX primitive we don't want to loose. We use the label text mechanism for translations.
