How to Convert Cups to Grams

Four steps to accurate kitchen conversions every time.

1

Identify your ingredient

Know exactly what you’re measuring — all-purpose flour, bread flour, and cake flour all have different densities and give different gram values.

2

Find the grams-per-cup density

Use ingredient-specific density: flour = 125g/cup, sugar = 200g/cup, butter = 227g/cup, honey = 340g/cup, rolled oats = 90g/cup.

3

Multiply cups × density

Grams = Cups × Density. Example: 1½ cups of flour = 1.5 × 125 = 187.5g. 2 cups of sugar = 2 × 200 = 400g.

4

Match your cup standard

Check which cup your recipe uses: US = 236.6ml, Metric = 250ml, UK = 284ml. Use the standard switcher in our calculator to match your recipe.

Frequently Asked Questions

Common questions about converting cups to grams and kitchen measurements.

1 US cup of all-purpose flour weighs 125 grams using the spoon-and-level method (spoon flour into the measuring cup and level with a knife). If you scoop directly, a cup can weigh up to 155g — a 24% difference that noticeably affects baking results. Other flours: bread flour = 127g, cake flour = 114g, whole wheat flour = 120g, almond flour = 96g per cup.
1 US cup of granulated sugar weighs 200 grams. Brown sugar (packed) = 220g, powdered/icing sugar = 120g, caster sugar = 200g, coconut sugar = 180g. For the best results with sugar, always measure by weight rather than volume, as sugar density varies significantly with humidity and packing.
1 US cup of butter weighs 227 grams, which equals exactly 2 US butter sticks (113.5g each) or 16 tablespoons. Half a cup of butter = 113.5g = 1 stick. Quarter cup = 57g = 8 tablespoons. When melted, butter weighs the same but takes slightly more volume due to density change.
No. A US customary cup is 236.6ml. The metric cup (Australia, Canada, South Africa) is 250ml — about 5.7% larger. The US legal cup (food labelling) is 240ml. The UK Imperial cup is 284.1ml — 20% larger than the US cup. Use our cup standard switcher to match the recipe you’re following.
Three reasons: (1) Different cup standards — US, metric, and UK cups are different sizes. (2) Different measuring methods — scooped flour vs spoon-and-level gives 20–25% different results. (3) Different ingredient variants — packed vs loose brown sugar, sifted vs unsifted flour. Cups2Grams uses the US customary cup (236.6ml) with the spoon-and-level method unless stated otherwise.
There are exactly 16 tablespoons in 1 US cup, and 3 teaspoons in 1 tablespoon (48 teaspoons per cup). Quick reference: ¼ cup = 4 tbsp, ⅓ cup = 5 tbsp + 1 tsp, ½ cup = 8 tbsp, ⅔ cup = 10 tbsp + 2 tsp, ¾ cup = 12 tbsp. Our calculator also shows the tablespoon equivalent alongside the gram result.
