Frequently Asked Questions

About 39.71 oz, based on cake flour having a density of 114g per cup. The exact amount depends on how the ingredient is measured and the specific product.
Multiply the number of tablespoons by 7.13 (grams per tablespoon for cake flour), then divide by 28.3495 to convert grams to ounces. For 158 tablespoons: 158 × 7.13 = 1,125.75g, then 1,125.75 ÷ 28.3495 = 39.71 oz.
For the most accurate results, weigh cake flour on a kitchen scale. If measuring by volume, sift or whisk first to break up clumps, then spoon into the measuring spoon and level off. Do not scoop directly from the bag.
Yes, quite a bit. If you spoon the flour into your measuring spoon and level it off, you will get about 114 grams per cup. If you dip directly into the flour bag and sweep level, the flour packs tighter and you can end up with 125.4 to 142.5 grams per cup instead. This conversion uses the spoon-and-level method, which is the standard most baking references follow.
Reverse the conversion: 39.71 oz × 28.3495 = 1,125.75g, then 1,125.75g ÷ 7.13 = 158 tablespoons. Or use the Ounces to Tablespoons converter.
