Does the window of an envelope count as a window?

Does any combination of molecules of liquid that would fill 236.588 milliliters of space count as a cup?

If there is more of the first one, resolves yes.

If there is more of the second one, resolves no.

I may base this on a somewhat smaller sample size (for example, only looking in my kitchen for my cups vs plates even if I might have something elsewhere)

You may add your own, but I reserve the right to shoot it down if needed or establish my own criteria.

I won't give a lot of personal info, but I do live with other people.
