I typically allow 300 - 350mm overhang for breakfast bar areas. You can get away with less but you'll be kicking the back of the units a bit more and may not be able to tuck stools away completely. Typical overhang of worktop on the door side is 20-25mm.
1 1 cup, uncooked equals 3 cups cooked. 2  1 cup, uncooked equals 3 cups cooked. 3  1 slice, dry equals 1/4 to 1/3 cup crumbs. 4  1 slice, soft equals 1/2 to 3/4 cup crumbs.  1 pound equals 3-1/2 to 4-1/2 cups shredded.
But that is a stupid answer. Just because something ways a pound, doesn't mean it is equivalent to 2 cups. Saying that 2 cups of anything equals a pound is like saying a cup of rocks equals a cups of feathers. Anyway, a pound of peanut butter typically ranges from 1 3/4 cup up to 2 1/4 cups. It really depends on the amount of fat in the product. the more fat the more it will weigh and the more volume it will take up.
