In this case by cup it probably actually refers to a pint glass of water (two measuring cups), but in any case not an exact measurement, so it doesn't make sense to give exact measurements. Its describing the vessels of transportation, not the amounts.

I meant the term basin, just pointing out how I didnt intuit what that was.

A) an open usually circular vessel with sloping or curving sides used typically for holding water for washing

B) chiefly British : a bowl used especially in cooking

C) the quantity contained in a basin spilled a basin of water on the floor

Not only is that not a measurement the US uses, the only geographical location mentioned in the definition is "chiefly British."

So, uh, "no."
