[Tagging] What is the unit of seamark:light:range?

[Jo]

There are 17912 objects tagged with "seamark:light:range" in our data. Not
a single one has a unit. They all seem to be in international nautical
miles. Do we add " nmi" to all of them? On the one hand being explicit
seems like the better solutio. On the other hand, who's  going to do it in
a verified manner in a reasonable timeframe?
