I don't think that questions like What is the measurement of 1 cup? add value to the site.
I don't even know why some people point others to heavy sites like Wolfram Alpha, when you can literally just ask Google, 1 cup in mL.
There's no end to the number of potential questions like these, they are extremely shallow and don't require any culinary knowledge to answer, and worst of all, we'll never rank as the first result because Google itself puts the answer at the top!
That means anybody who searches for a question like this will never even bother clicking on the link to our site, because the answer is already sitting right there in front of them. In other words, they don't help veteran members who know where to look this stuff up, and they don't help attract new visitors either.
This is a subset of general reference questions, but I think an even more pathological case, since you can not only find the answer on a general reference source but also in millions of pages, sites, and apps dedicated to exactly this purpose. We're not covering the long tail here, it's one of the most heavily-diluted areas I can think of.
I can only think of two exceptions, those being:
Archaic weights and measurements. However, if we want to cover these, I think a single question linking to an heirloom weights and measurements chart suffices to cover the entire category; and
Subjective or approximate measurements, like a knob of butter.
Does anyone disagree that, aside from the above two exceptions, these questions should be summarily closed?
