How Much Is 1.5 Cups of Oat Flour in Grams?
1.5 cups of oat flour weighs 138.00 g. This is based on oat flour having a density of 92g per cup. Because cups measure volume and grams measure weight, the result depends on the ingredient, and a different ingredient would give a different result for the same 1.5 cups.
Formula and Step-by-Step
- Start with 1.5 cups of oat flour
- 1 cup of oat flour = 92g
- 1.5 × 92 = 138g
The same formula works for any amount. Multiply (or divide) by the density, then convert units as needed.
Measuring Tip
For the most consistent results, weigh oat flour on a kitchen scale. Volume measurements can vary by 20-30% depending on how the flour is scooped.
Oat Flour at Different Amounts
How oat flour scales across common cups measurements. Your amount (1.5 cups) is highlighted.
For reference, 1.5 cups of oat flour (138g) is close in weight to a baseball (145g).

Understanding the Units
What is a Cup?
In US cooking, a cup measures volume, not weight. One standard US cup holds 236.588 ml of liquid. Because different ingredients have different densities, a cup of one ingredient can weigh very differently from a cup of another.
What is a Gram?
Weighing ingredients in grams eliminates the variability of volume measurements. A cup of flour can weigh anywhere from 120g to 160g depending on how it was scooped, but 120g of flour is always 120g of flour.
