Pai's Kitchen recipes list ingredients in grams first — the accurate way to bake — with US measures alongside. This converter handles the eight ingredients home cooks convert most, using standard cup weights for each. Pick the ingredient: a cup of flour and a cup of honey do not weigh the same, and that difference is exactly why recipes fail.
A cup is a volume; a gram is a weight. Flour scooped from the bag can pack anywhere from 100 to 160 grams into the same cup depending on technique — a 60% swing in the main ingredient of a cake. That is why the Bánh Bông Lan sponge in our collection specifies 120 g of flour, not 'about a cup'. For soups and marinades, cups are fine. For baking, weigh once and the recipe becomes repeatable forever.
Standard reference weights per US cup: flour 125 g, granulated sugar 200 g, butter 227 g, cocoa powder 100 g, uncooked rice 185 g, milk and water 240 g, cooking oil 218 g, honey 340 g. Try it on the collection: the Bánh Bao dough (280 g flour) is about 2¼ cups; the Thịt Nướng marinade's 20 g fish sauce is roughly 4 teaspoons. Every recipe in the Pai Recipes app carries grams, US measures and ounces together.
About 125 g for all-purpose flour, spooned and levelled. Scooping straight from the bag packs in more — which is why our recipes weigh.
No: a US cup is 236.6 ml; a metric cup is 250 ml. This converter uses US cups, matching our recipes' US measures.
Densities vary by ingredient and even by brand for some foods. The eight here cover the great majority of home baking and cooking conversions; for anything else, weigh it once and note your own figure.
