How Much Is 138 Grams of All-Purpose Flour in Cups?
138 grams of all-purpose flour equals 1.10 cups. All-purpose flour has a density of 125.16g per cup. Because grams measure weight and cups measure volume, the result depends on the ingredient's density.
Formula and Step-by-Step
- Start with 138 grams of all-purpose flour
- 1 cup of all-purpose flour = 125.16g
- 138g ÷ 125.16g/cup = 1.10 cups
The same formula works for any amount. Multiply (or divide) by the density, then convert units as needed.
Measuring Tip
Humidity affects all-purpose flour weight. In humid conditions, flour absorbs moisture and weighs more per cup. Store it in an airtight container for consistent results.

Understanding the Units
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.
What is a Cup?
There are three cup standards used worldwide. The US cup (236.588 ml) is used in American recipes. The metric cup (250 ml) is standard in Australia, New Zealand, and some parts of Asia. The imperial cup (284.131 ml) appears in older British and Canadian recipes. A metric cup holds about 5.7% more than a US cup, while an imperial cup holds about 20% more. Using the wrong standard can noticeably affect a recipe.
