Thank you, Max, for the effort and Hans for a core solution!

Not to be misunderstood, I couldn’t check yet, maybe I wasn’t clear:

I need to process the measure as a dimension, like \measured{Bleed}.

As far as I tried, neither tex.measured nor context.measured worked (but 
I wouldn’t swear on it, maybe I had a different error).
