Cups to grams chart

Grams per US cup for all 29 ingredients. Cocoa powder and honey are both one cup and four times apart in weight, which is the whole case for a scale.

How to measure flour without a scale

Fluff the flour in its bag with a fork, spoon it loosely into the cup until it mounds over the rim, then sweep the top level with the back of a knife. Tapping or pressing packs it down and quietly adds 15–25%.

Recipes that mix units

Recipes from videos are the worst for it: cups for the flour, grams for the butter, a splash of milk. Convert only the lines you need. The recipe scaler does the resizing.

Based on the US cup (236.6 ml), spooned and levelled, with weights from published test-kitchen values where they exist. Sources: the NIST capacity table and King Arthur Baking’s ingredient weight chart. Tap an ingredient to load it into the converter.

Common questions

How many grams is 1 cup of flour?

120 g for all-purpose or plain flour, spooned into the cup and levelled. Scoop the cup straight into the bag and you compress the flour to 145 g or more, over 20% extra, which is enough to turn a tender cake dry.

Why can’t I use one cups-to-grams number for everything?

A cup measures volume and a gram measures weight, and the bridge between them is density. A cup of cocoa powder weighs 85 g; a cup of honey weighs 340 g. That fourfold gap from the same measuring cup is why any single conversion factor is wrong for almost every ingredient.

Is a US cup the same as a metric cup?

No. A US cup is 236.6 ml, a metric cup is 250 ml and an imperial cup is 284 ml. The 6% gap between US and metric disappears in a stew, but it changes the hydration of bread dough or pastry.

Should I weigh ingredients instead of using cups?

For baking, yes. A scale avoids differences caused by packing a measuring cup, and it’s less washing up too, since you can tare between ingredients in one bowl.

How do I convert a recipe that only gives cups?

Convert each ingredient with its own density, which is what this converter does. If you’re changing the yield as well, scale the list first and convert after, so the rounding happens once.
