1 × 2.5 = 2.5g
Convert grams to ounces: 2.5 ÷ 28.3495 = 0.09 oz

The same formula works for any amount. Multiply (or divide) by the density, then convert units as needed.

Frequently Asked Questions

About 0.09 oz, based on self-rising flour having a density of 120g per cup. The exact amount depends on how the ingredient is measured and the specific product.

What is the formula for converting teaspoons of self-rising flour to ounces? expand_more

How do I measure self-rising flour accurately? expand_more

For the most accurate results, weigh self-rising 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.

Does the measurement method affect how much self-rising flour weighs per cup? expand_more

Yes, quite a bit. If you spoon the flour into your measuring spoon and level it off, you will get about 120 grams per cup. If you dip directly into the flour bag and sweep level, the flour packs tighter and you can end up with 132 to 150 grams per cup instead. This conversion uses the spoon-and-level method, which is the standard most baking references follow.
