How Much Is 1 Teaspoon of All-Purpose Flour in Ounces?
1 teaspoon of all-purpose flour equals 0.09 oz. All-purpose flour has a density of 125.16g per cup (2.61g per teaspoon), which means it's relatively light compared to other common cooking ingredients. For comparison, 1 teaspoon of honey would be 0.25 oz.
Formula and Step-by-Step
- Start with 1 teaspoon of all-purpose flour
- 1 teaspoon of all-purpose flour = 2.61g
- 1 × 2.61 = 2.61g
- Convert grams to ounces: 2.61 ÷ 28.3495 = 0.09 oz
The same formula works for any amount. Multiply (or divide) by the density, then convert units as needed.
