View table →Frequently Asked Questions
Why do cup-to-gram conversions differ by ingredient?
Because every ingredient has a different density. A cup of honey weighs around 340 g, while a cup of flour is only about 120 g. That's why ingredient-specific tables are essential for accurate baking.
Which cup size do these tables use?
All tables use the US standard measuring cup of 236.6 ml. Metric (250 ml) and UK imperial (284 ml) cups are shown in the comparison chart on each ingredient page.
What's the difference between spooned and dipped flour?
Spooning means lightly filling the cup with a spoon and leveling it off — the King Arthur Baking standard. Dipping scoops directly and compacts the flour, adding up to 18% more grams. We recommend the spooned method for consistent results.
Where do the density values come from?
Flour and sugar densities come from the King Arthur Baking Weight Chart; liquids and other ingredients from the USDA FoodData Central database. Every source is linked on the individual ingredient page.
Can I convert grams back to cups?
Yes. Each ingredient page includes a reverse grams-to-cups table. For custom amounts, use the Kitchen Unit Converter, which accepts direct input in g, oz, ml, tablespoons, and more.
Are the tables valid outside the US?
The primary values use US cups (236.6 ml). Each page shows a system comparison chart covering US legal (240 ml), metric (250 ml), and UK imperial (284 ml) so you can pick the right size for your recipe.
Why is water simpler to convert?
Water has a density of exactly 1 g/ml, so 250 ml equals exactly 250 g in the metric system. For flour, sugar, and other dry ingredients the density varies — that's where grams tables become indispensable.
