(I assume nobody brins a measuring cup)

Not quite everyone. I carry a GSI Cascadian plastic cup with the handle cut off. It is sturdy, easy on the lips with hot drinks, non-toxic and it weighs 1.6 oz. It has measurements from 1/2 to 1-1/2 cups cast into the inside of the cup. This is both my hot drink cup and my measuring cup.
