Formula and Step-by-Step

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

Start with 2 teaspoons of rolled oats
1 teaspoon of rolled oats = 1.88g
2 × 1.88 = 3.75g
Convert grams to ounces: 3.75 ÷ 28.3495 = 0.13 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.
