How Much Is 1.25 Tablespoons of Cornstarch in Ounces?
1.25 tablespoons of cornstarch equals 0.35 oz. Cornstarch has a density of 128g per cup (8g per tablespoon), which means it's relatively light compared to other common cooking ingredients. For comparison, 1.25 tablespoons of honey would be 0.94 oz.
Formula and Step-by-Step
- Start with 1.25 tablespoons of cornstarch
- 1 tablespoon of cornstarch = 8g
- 1.25 × 8 = 10g
- 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
Humidity affects cornstarch weight. In humid conditions, flour absorbs moisture and weighs more per cup. Store it in an airtight container for consistent results.

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?
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.
