Ever pulled a cake out of the oven only to find it denser than a brick? Chances are, your flour measurement was off. Measuring flour by volume (cups) is like guessing how many marbles fit in a jar—it’s easy to overpack or underfill. That’s where grams save the day. In this guide, you’ll learn exactly how to convert cups to grams for all-purpose flour, why it matters, and how to avoid common baking blunders.
Unit definitions
What is a cup (cups)?
- Description: A cup is a unit of volume used primarily in the United States for cooking.
- Symbol: c or cups
- Common uses: Measuring dry and liquid ingredients in recipes.
- Definition: 1 US cup = 236.588 mL, but flour’s weight varies due to settling.
What is a gram (g)?
- Description: A gram is a metric unit of mass.
- Symbol: g
- Common uses: Precise ingredient measurements in baking and science.
- Definition: 1 gram = 0.001 kilograms. For all-purpose flour, 1 cup ≈ 125g.
Conversion formula
Grams = Cups × 125
For example, 2 cups of flour = 2 × 125 = 250g. To convert grams back to cups, divide by 125: 300g ÷ 125 = 2.4 cups.
Example calculations
- Converting 2.5 cups to grams:
2.5 cups × 125g/cup = 312.5g - Converting 400g to cups:
400g ÷ 125g/cup = 3.2 cups

Historical background
The cup measurement became popular in early 20th-century American cookbooks, like Fannie Farmer’s 1896 Boston Cooking-School Cook Book. Meanwhile, grams dominated European recipes due to the metric system’s precision . Bakers worldwide now blend both systems, especially with online recipe sharing.
Interesting facts
- Why weight wins: A cup of flour can weigh 30% more if packed tightly versus spooned.
- Flour’s identity crisis: All-purpose flour’s density ranges from 120–130g per cup based on humidity.
- The cup’s origin: Ancient civilizations used literal cups or bowls for measurements.
- Celebrity baker secret: Paul Hollywood insists on grams for The Great British Bake Off precision.
- Humidity’s role: In muggy climates, flour absorbs moisture, making it heavier per cup.
FAQ
Grams measure weight, which is more accurate than volume. Flour settles in cups, causing inconsistent measurements.
Spoon flour into the cup and level it with a knife. Avoid tapping or compacting.
Yes. Whole wheat flour is denser (1 cup ≈ 130g), while cake flour is lighter (1 cup ≈ 115g).
It’s better to use dry measuring cups, but if you must, fluff the flour first to prevent packing.
Use the spoon-and-level method consistently. For best results, consider buying an affordable scale.
