How Much Is 4 Teaspoons of Self-Rising Flour in Ounces?

4 teaspoons of self-rising flour weighs 0.35 oz. This is based on self-rising flour having a density of 120g per cup. Because teaspoons measure volume and ounces measure weight, the result depends on the ingredient, and a different ingredient would give a different result for the same 4 teaspoons.

Formula and Step-by-Step

teaspoons × 2.5g/tsp ÷ 28.3495g/oz = ounces
  1. Start with 4 teaspoons of self-rising flour
  2. 1 teaspoon of self-rising flour = 2.5g
  3. 4 × 2.5 = 10g
  4. Convert grams to ounces: 10 ÷ 28.3495 = 0.35 oz

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

Measuring Tip

Different flour types have very different weights per cup. Always check the specific flour your recipe calls for rather than using a generic "flour" conversion.

Understanding the Units

What is a Teaspoon?

A US teaspoon is 4.929 ml, a metric teaspoon is exactly 5 ml, and an imperial teaspoon is 5.919 ml. The metric and US versions are nearly identical (1.4% difference), but the imperial teaspoon is 20% larger. For most spices the difference is negligible, but for leaveners like baking powder it can affect the result.

What is an Ounce?

An ounce (oz) is a US customary unit of weight equal to 28.3495 grams or 1/16 of a pound. In cooking, "ounces" refers to weight (avoirdupois ounces), not fluid ounces which measure volume.

Frequently Asked Questions

About 0.35 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.
Multiply the number of teaspoons by 2.5 (grams per teaspoon for self-rising flour), then divide by 28.3495 to convert grams to ounces. For 4 teaspoons: 4 × 2.5 = 10g, then 10 ÷ 28.3495 = 0.35 oz.
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.
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.
