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.
A 1 cup measuring cup is divided into 8 fluid ounces. One pound is divided into 16 ounces. I think its very unfortunate that the idiots who invented the English System gave the same unit name (ounces) to both volume and weight! A cup of lead pellets and cup of feathers both occupy 8 fluid ounces of volume. However, the pellets will weigh a lot more than 8 ounces on a scale. The feathers will weigh a lot less than 8 ounces on a scale. This is due to density differences. If a recipe calls for 4 oz of flour, this means use a scale, not a half cup measure. 4 oz of flour will fill about 1 cup (8 fluid ounces). A cup of sifted flour will weigh a lot less than a cup of unsifted flour.
