Formula and Step-by-Step

teaspoons × 3.33g/tsp ÷ 28.3495g/oz = ounces
  1. Start with 150 teaspoons of steel cut oats
  2. 1 teaspoon of steel cut oats = 3.33g
  3. 150 × 3.33 = 500g
  4. Convert grams to ounces: 500 ÷ 28.3495 = 17.64 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?

A US teaspoon is 4.929 ml, a metric teaspoon is exactly 5 ml, and an imperial teaspoon is 5.919 ml. The metric and US versions are nearly identical (1.4% difference), but the imperial teaspoon is 20% larger. For most spices the difference is negligible, but for leaveners like baking powder it can affect the result.

What is an Ounce?

Ounces are commonly used in US recipes for cheese, meat, chocolate, and other ingredients sold by weight. Many kitchen scales offer both gram and ounce readings.

Frequently Asked Questions

About 17.64 oz, based on steel cut oats having a density of 160g per cup. The exact amount depends on how the ingredient is measured and the specific product.
Multiply the number of teaspoons by 3.33 (grams per teaspoon for steel cut oats), then divide by 28.3495 to convert grams to ounces. For 150 teaspoons: 150 × 3.33 = 500g, then 500 ÷ 28.3495 = 17.64 oz.
For the most accurate results, weigh steel cut oats on a kitchen scale. If measuring by volume, spoon the ingredient into the measuring spoon and level it off with a straight edge rather than scooping directly.
Weight-per-cup values vary because of differences in how the ingredient is measured (spooned vs scooped), grind size, moisture content, and settling during storage. Our values use standardized measurement methods from established culinary references.
