Formula and Step-by-Step
- Start with 138 grams of pearl barley
- 1 cup of pearl barley = 200g
- 138g ÷ 200g/cup = 0.69 cups
The same formula works for any amount. Multiply (or divide) by the density, then convert units as needed.
Measuring Tip
Pour grains into the measuring cup and level off. Do not shake or tap, as this settles the grains and increases the weight.
