Frequently Asked Questions (Baking Conversion Guide)
Everything you need to know about ingredient density and global cup measurement standards.
How many grams are in 1 cup, 1/2 cup, and 3/4 cup of flour?▼
Because flour is aerated, 1 US cup of all-purpose flour equals 120 grams. For other common recipe quantities: 1/2 cup of flour is 60 grams, 3/4 cup of flour is 90 grams, 1.5 cups of flour in grams is 180g, and flour 2 cups to grams equals 240g. When reversing measurements to turn grams into cups: 100g flour in cups is approx. 0.83 cups (5/6 cup), 300g flour in cups is 2.5 cups, and 500 gm flour to cups is approx. 4.17 cups.
How do I convert 1 cup of sugar vs 1 cup of butter to grams?▼
Density determines how heavy an ingredient is per cup measure. For granulated sugar, 1 cup in grams sugar equals 200g (so half a cup how many grams is 100g sugar). For unsalted butter, 1 cup equals 227g, so 1/2 cup of butter in grams equals 113.5g (1 American stick). Powdered sugar is lighter at 120g per cup, while packed brown sugar is heavier at 220g per cup.
What is the difference between US cups, UK cups, and metric cups in grams?▼
Global recipes use different cup volumes. Standard American cup grams are based on a 240ml US Customary cup. Metric cups (used in Australia, New Zealand, and South Africa) hold 250ml (about 4% larger than US cups). Imperial UK cups hold 284ml (about 18% larger). Our calculator handles grams to american cups and metric cup to grams conversions automatically based on your selected region.
How can I convert grams to cups without a kitchen scale?▼
To perform a clean g to cup conversion or transfer cups to grams without a digital scale, use our ingredient-specific conversion table. When measuring dry ingredients like flour, always use the "spoon and level" technique: fluff the flour, spoon it into the cup measure gently without packing it down, and sweep a straight edge across the rim.
