Convert Cups to Grams

This page opens the cooking converter preset to cups → grams with flour selected. There is no universal answer to "how many grams in a cup" — it depends entirely on the ingredient. A US cup holds 240 ml, so the weight is 240 ml times the ingredient's density: about 127 g for all-purpose flour (0.53 g/ml), 204 g for granulated sugar (0.85 g/ml), 219 g for butter (0.911 g/ml) and 341 g for honey (1.42 g/ml).

That spread is why flour and sugar can never share one conversion number: flour traps air between fine particles, so a cup of it is mostly much lighter than a cup of dense syrup or packed sugar. Pick your ingredient from the list and the converter applies its real density — the result line shows which density was used so you can compare it with your recipe's own chart.

Keep in mind that volume measures of powders are inherently approximate: scooped and tapped flour can weigh 10–20% more than gently spooned flour. For bread and pastry where hydration matters, treat the converted grams as a starting point and prefer a scale when the recipe gives weights. For soups, sauces and everyday cooking, the converted value is plenty accurate.
