How Much Is 18 Teaspoons of Granulated Sugar in Ounces?
18 teaspoons of granulated sugar weighs 2.65 oz. This is based on granulated sugar having a density of 200g 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 18 teaspoons.
Formula and Step-by-Step
- Start with 18 teaspoons of granulated sugar
- 1 teaspoon of granulated sugar = 4.17g
- 18 × 4.17 = 75g
- Convert grams to ounces: 75 ÷ 28.3495 = 2.65 oz
The same formula works for any amount. Multiply (or divide) by the density, then convert units as needed.
Measuring Tip
Granulated sugar should be spooned into the measuring spoon and leveled off. Do not pack it unless the recipe specifically says to (packing is only standard for brown sugar).

Understanding the Units
What is a Teaspoon?
One teaspoon holds about 5 milliliters. There are 3 teaspoons in a tablespoon and 48 teaspoons in a cup. Teaspoon accuracy matters most with leaveners like baking powder and baking soda, where small differences affect rise and texture.
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.
