A yard is the distance from the King's nose to the thumb of his outstretched arm.i shall treat that question with the contempt it deserves!.
(more seriously i dont actually know the volume of a US pint without googling (it is less than 500ml tho) but the uk one is 568ml
and a yard is (a tiny bit under) 2.5 pints (and comes in the most interesting beer glass shape i have ever seen)
edit.... pint question already answered better than i managed. i should have read whole thread 1st!.
