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.
I guess that would really depend on how tightly packed they are, but in general: There are 8 ounces in a cup. There are 16 ounces in a pound. There are 4 cups in a quart. So, 16 ounces is 2 cups. Multiply that by 2 (to make 4 cups) and you have 2 pounds. Therefore, 1 quart should weigh approximately 2 pounds. However, that really is a liquid measurement. Loosely packed blueberries would probably weigh less than that.
