Formula and Step-by-Step

teaspoons × 1.88g/tsp ÷ 28.3495g/oz = ounces

Start with 1.5 teaspoons of rolled oats
1 teaspoon of rolled oats = 1.88g
1.5 × 1.88 = 2.81g
Convert grams to ounces: 2.81 ÷ 28.3495 = 0.10 oz

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

Measuring Tip

Oats come in multiple forms (rolled, steel-cut, instant) that have different densities. Steel-cut oats are nearly twice as heavy per cup as rolled oats.

Understanding the Units

What is a Teaspoon?

In baking, teaspoon measurements are critical for ingredients where precision changes the outcome. Too much baking soda (1 tsp = 6g) creates a metallic taste, while too little means flat results.

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.
