Convert weight to cups for any ingredient.
1 pound = 453.6 grams = 16 ounces. Cups per pound varies by ingredient: flour ~3.6 cups/lb, sugar ~2.3, butter 2.0 (4 sticks), rice ~2.5, oats ~3.5. When buying ingredients in bulk by weight, knowing these conversions helps you estimate how many recipes you can make. A 5-pound bag of flour (~18 cups) makes approximately 6-8 standard bread loaves or 4-5 batches of cookies. A 4-pound bag of sugar (~9 cups) handles about 6 standard cake recipes. For consistent results, measure by weight rather than cups whenever possible.
