How to Measure All-Purpose Flour Accurately (Spoon & Level Method)
Converting cups of all-purpose flour to grams is the single most important adjustment you can make for consistent baking. Because flour is a fine, compressible powder, its bulk density shifts dramatically depending on whether it has settled in the bag, absorbed ambient humidity, or been scooped directly with a measuring cup.
According to USDA FoodData Central (FDC ID 169761), 1 US Customary cup (236.59 mL) of unsifted all-purpose wheat flour weighs 125 grams (4.41 oz), corresponding to a bulk density of 0.5283 g/mL. If you are following a recipe written for King Arthur Baking Company's test kitchen, their official spooned-and-leveled standard is 120 grams per US cup (0.5072 g/mL). Meanwhile, a Commonwealth Metric cup (250 mL) holds 132.1 grams of flour at USDA density.
Step-by-Step Kitchen Measuring Technique
Professional bakers and test kitchens never dip the measuring cup directly into the flour bin unless a recipe explicitly specifies the 'dip-and-sweep' method.
- Fluff and aerate: Stir the flour inside its bag or canister with a whisk, fork, or spoon to break up compacted pockets formed during storage.
- Spoon lightly into the cup: Using a large spoon, gently transfer spoonfuls of aerated flour into your dry measuring cup until it forms a slight mound above the rim. Do not shake or tap the cup on the counter.
- Level with a straight edge: Sweep the back of a flat dinner knife or bench scraper straight across the rim of the measuring cup so excess flour falls back into the container.
Culinary & Baking Notes for All-Purpose Flour
- All-purpose flour vs. cake flour: Cake flour and pastry flour are milled finer and contain less protein, weighing about 114–120 g per US cup, whereas bread flour weighs 125–127 g per US cup.
- Sifted flour vs. flour, sifted: '1 cup sifted flour' means sift before measuring (~110–115 g), while '1 cup flour, sifted' means measure 1 cup (125 g) first and then sift it into the bowl.
- Humidity effect: On humid summer days, wheat flour absorbs moisture from the air and packs more densely; weighing in grams automatically compensates for fluffiness changes.
US Cup vs. Metric Cup vs. UK Cup Weight for All-Purpose Flour
If you are adapting an international recipe, remember that cup sizes vary by country. Here is how much 1 cup of all-purpose flour weighs across all four global cup standards (at ρ = 0.5283 g/mL):

Frequently Asked Questions About All-Purpose Flour Conversions
How many grams are in 1 cup of all-purpose flour?
1 US Customary cup (236.59 mL) of all-purpose flour weighs 125 grams (4.41 oz) according to USDA FoodData Central, or 120 grams (4.25 oz) using the King Arthur Baking spooned-and-leveled chart. If you use a 250 mL Metric cup (UK, Australia, NZ, Canada), 1 cup of flour weighs 132.1 grams.
Why does King Arthur say 120g per cup of flour while USDA says 125g?
Both measurements are accurate for their testing methods. USDA FoodData Central (125 g/cup) reflects average consumer spooned unsifted flour, while King Arthur Baking (120 g/cup) aerates the flour thoroughly before lightly spooning and leveling. You can switch between both standards in the converter above.
How many tablespoons are in 1/4 cup or 50 grams of flour?
1/4 US cup of flour equals 4 tablespoons and weighs 31.25 grams (at 125 g/cup). Conversely, 50 grams of all-purpose flour equals 0.4 US cups, or about 6.4 US tablespoons (6 tablespoons + 1 ¼ teaspoons).
Does self-rising flour weigh the same as all-purpose flour?
Self-rising flour contains baking powder and salt blended into soft wheat flour. It is slightly lighter when aerated, averaging 113–125 grams per US cup depending on the brand.
