Please explain your measurements: Substitute for King Arthur Flour Gluten-Free Multi-Purpose Flour Stabilized brown rice flour 6 cps = 6 x 8 oz = 48 oz in Canada...you quote 32 oz Potato Starch 2 cps = 2 x 8 oz = 16 oz in Canada...you quote 10 3/4 oz Tapioca starch 1 cp = 8 oz in Canada...you quote 4 oz No where can I find these equivalents whether in US, UK or Canada. Thank you. The type of flour will influence the weight of 1 cup. Here is the Master Weight Chart. Frank @ KAF. Norma, water and many liquids weigh 8 ounces per cup, but this isn't necessarily true of dry ingredients. Flour can weigh anywhere from about 3 3/4 to 4 1/2 ounce per cup, when measured with the "sprinkle and sweep" method, which is how we measure when developing our recipes. Hope this helps - PJH
