that wikipedia page is quite messed up by an recent edit war about the
use
of "free climbing" in different parts of the world, the current version
is historically wrong.
Certainly, it doesn't match the historical use in my country either.

You might even add a converted grade (although the conversion isn't
unique since 5.13 might be anything between 7c+ and 8b):
No! Conversion of grades is subjective and can be done by the
data consumer. The grade should be in the native system of the
area. We also do not convert maxspeed=15mph into km/h tags, since
that can be computed.

Sorry, I wasn't specific enough here; I meant if there is an official
converted grade.
In my area the guidebooks usually have two grades for each route;
Norwegian grades and French grades. In such cases, when there is an
"official conversion" (but doesn't really match the conversion tables on
e.g. the wiki-link above [1]), I think both can be added.
Then the data consumer can choose which one to use: If you want to use
the official French grade, do it. If you want to do the conversion
yourself, try converting from the Norwegian grade.
For a non-subjective conversion such as mph to km/h, conversion can be
up to the data consumer (the result will anyway be the same).
