It'd be an even better example if there was an equivalent conversion function on Wikifunctions to link to. There doesn't appear to be one yet.
The project's response to the funding Google.org Fellows' evaluation is a deeper explanation that explicitly compares the goals of Wikifunctions to Scribunto (those Lua functions) — and is especially notable in the context of replacing templates and Lua modules since Google.org made a bunch of recommendations to further decouple Abstract Wikipedia's goals from Wikifunctions that Wikimedia thanked them for and subsequently ignored: https://meta.wikimedia.org/wiki/Abstract_Wikipedia/Google.or...
The catalogue of functions useful to Wikimedia is much more prosaic than the {{Convert}} template and in line with the Google.org examination — it's more about Abstract Wikipedia's goals of natural language generation (NLG): https://www.wikifunctions.org/wiki/Wikifunctions:Catalogue

The list of all functions is also similarly lower level; language transformations, form validation, sub/string operations: https://www.wikifunctions.org/wiki/Special:ListObjectsByType...
