Recipes that use the metric or British Imperial system measure many ingredients by weight instead of volume. This can be confusing and a little frustrating for those used to measuring in cups, not ounces or grams. Those used to the metric system acquire food scales to measure for recipes. But if your only tools are measuring cups and tablespoons, there is still a way to determine the weight of flour. By knowing the weight of flour itself, you can calculate the weight needed for a recipe using volume and skip the scales completely.
Things You'll Need
- Measuring cups
Learn the weight per cup of the type of flour you are using. All purpose flour, for example, weighs 4 ounces. or 110 grams per cup. For a quick guide to the weights of commonly used flours, check out the tips section below.
Learn the weight per teaspoon or tablespoon of the type of flour you are using. Sometimes, flour is used in small amounts that are more easily calculated by knowing the weight of a teaspoon of flour. Once cup equals 48 teaspoons or 16 tablespoons. Use these ratios to determine smaller increments of weight. For example, 1 tablespoon of all-purpose flour weighs 18 and1/3 grams each (because 110 grams divided by 16 equals 18.3).
Determine the amount of flour you need. Divide the weight listed in the recipe by the weight of each cup. For example, if your recipe calls for 247.5 grams of all-purpose flour, divide 247.5 by 110 (the number of grams in a cup of flour). The result is 2.25 or 2 and 1/4 cups of flour.
Tips & Warnings
- Buckwheat and potato flour each weigh 6 ounces or 175 grams per cup. Rice flour weighs 5 ounces or 150 grams per cup. Rye flour weighs 3.5 ounces or 100 grams per cup. Wheat/wholemeal flour weighs 4.5 ounces or 25 grams per cup.
