IMO, trying to duplicate Wikipedia's complexity isn't worth the effort. Hundreds of people have worked on those templates over the years and it's hard to copy over 1 of them without needing hundreds of others.

You can simply hard code the numbers into the infobox since the conversions will never change and call it a day. :)
