I intend to orphan the convertall package.

Recent versions have migrated from Qt to flutter so it doesn’t make much
sense (nor the team has the required knowledge) to maintain it under the
Qt/KDE Team’s umbrella anymore.

The package description is:
 With ConvertAll, you can convert any unit in the large database to any other
 compatible unit. If you want to convert from inches per decade, that's fine.
 Or from meter-pounds. Or from cubic nautical miles. The units don't have to
 make sense to anyone else.
