How Much Is 1 Tablespoon of Rolled Oats in Ounces?
1 tablespoon of rolled oats weighs 0.20 oz. This is based on rolled oats having a density of 90g per cup. Because tablespoons measure volume and ounces measure weight, the result depends on the ingredient, and a different ingredient would give a different result for the same 1 tablespoon.
Formula and Step-by-Step
- Start with 1 tablespoon of rolled oats
- 1 tablespoon of rolled oats = 5.63g
- 1 × 5.63 = 5.63g
- Convert grams to ounces: 5.63 ÷ 28.3495 = 0.20 oz
The same formula works for any amount. Multiply (or divide) by the density, then convert units as needed.
Measuring Tip
Uncooked and cooked grains have completely different weights per cup. These conversions are for uncooked/dry grains unless specified otherwise.

Understanding the Units
What is a Tablespoon?
One tablespoon holds about 15 milliliters. There are 16 tablespoons in a cup and 3 teaspoons in a tablespoon. In baking, tablespoon measurements are used for butter, oil, honey, and other ingredients where a full cup would be too much.
What is an Ounce?
Weight ounces and fluid ounces are different measurements. A fluid ounce measures volume (29.574 ml), while an ounce measures weight (28.35g). They only align for water, where 1 fl oz weighs approximately 1 oz.
