Frequently Asked Questions

About 69.53 oz, based on all-purpose flour having a density of 125.16g per cup. The exact amount depends on how the ingredient is measured and the specific product.
Multiply the number of cups by 125.16 (grams per cup for all-purpose flour), then divide by 28.3495 to convert grams to ounces. For 15.75 cups: 15.75 × 125.16 = 1,971.27g, then 1,971.27 ÷ 28.3495 = 69.53 oz.
For the most accurate results, weigh all-purpose flour on a kitchen scale. If measuring by volume, sift or whisk first to break up clumps, then spoon into the measuring cup and level off. Do not scoop directly from the bag.
Yes, quite a bit. If you spoon the flour into your measuring cup and level it off, you will get about 125.16 grams per cup. If you dip directly into the flour bag and sweep level, the flour packs tighter and you can end up with 137.68 to 156.45 grams per cup instead. This conversion uses the spoon-and-level method, which is the standard most baking references follow.
Reverse the conversion: 69.53 oz × 28.3495 = 1,971.27g, then 1,971.27g ÷ 125.16 = 15.75 cups. Or use the Ounces to Cups converter.
