mittauksten
I’m not finding an established concept or term "mittauksten" in reliable sources. It may be a misspelling, a niche/local term, or a neologism. Could you share the intended language, field, or a bit more context (for example, is it related to measurement, surveying, linguistics, or something else)? With that, I can write a precise, neutral wiki-style article.
If you’d like, I can also produce a neutral stub that clearly notes the term’s uncertain status,
