Why Cups to Grams Matters for Baking
Measuring by weight (grams) is far more accurate than measuring by volume (cups). A cup of flour can vary by 30–50 grams depending on how tightly it's packed. For baking, where precision matters, always weigh your ingredients.
Common Conversions
- 1 cup all-purpose flour = 125 g (spooned and leveled)
- 1 cup granulated sugar = 200 g
- 1 cup butter = 227 g (2 sticks)
- 1 cup brown sugar (packed) = 220 g
- 1 cup water = 237 g
Tips for Accurate Measuring
- Spoon and level flour into the cup rather than scooping, which compresses it.
- Pack brown sugar firmly into the cup.
- Use a kitchen scale whenever possible for the best results.
Frequently Asked Questions
How many grams are in 1 cup of flour? +
One cup of all-purpose flour weighs 125 grams. Bread flour is slightly heavier at 130g, while cake flour is lighter at 100g. The difference adds up in baking — if a recipe calls for 3 cups of flour that's already a 90g swing depending on which flour you use.
Does 1 cup always weigh the same? +
No — volume stays constant but weight varies significantly by ingredient density. One cup of white sugar weighs 200g, while one cup of flour is only 125g. This 60% difference is exactly why grams are more reliable than cups for consistent baking results.
US cups vs. metric cups — does the difference matter? +
A US cup is 236.6 mL while an Australian or metric cup is 250 mL — about 5.6% larger. For soups and sauces, the difference is negligible. But in baking, especially for flour or leaveners, you may want to adjust by about 1 tablespoon per cup when using recipes from Australia or New Zealand.
How do I measure flour accurately by cup if I don't have a scale? +
Spoon flour lightly into the measuring cup and level it off with a straight edge — never scoop directly from the bag. Scooping compacts the flour and can add 20–30% extra weight without you realising it. That said, a basic kitchen scale (around $10–$15) is the single best upgrade for consistent baking.
