Cups to Grams Chart
A cup is a volume; a gram is a weight — so a cup of flour (120 g) weighs barely half a cup of honey (340 g). This chart converts US cups to grams for 30 baking ingredients, with half-, third-, and quarter-cup and tablespoon columns, plus a live converter below. Print it, tape it inside a cabinet door, and stop guessing.
The chart: US cups to grams
Values are grams per US cup (236.6 ml), spooned-and-leveled — the standard American measuring method. A metric cup (250 ml, used in Australia and many international recipes) is about 6% larger: multiply by 1.057. 2 cups of all-purpose flour = 240 g.

Output · formula · meaning
| Output | Formula | What it means |
|---|---|---|
| Grams | cups × grams-per-cup | 2 cups of all-purpose flour = 240 g. |
| Cups | grams ÷ grams-per-cup | 340 g of honey = 1 cup (340 ÷ 340). |
| Tablespoon | grams-per-cup ÷ 16 | There are 16 tbsp in a cup: 1 tbsp of flour = 7.5 g. |
| Metric-cup adjustment | US-cup grams × 1.057 | International recipes using a 250 ml cup need ~6% more weight. |
Who uses this
- Home bakers: converting American cup recipes to a kitchen scale — the single biggest accuracy upgrade in baking.
- Sourdough & bread bakers: flour varies most by measuring method; weighing ends the dense-loaf mystery.
- Meal preppers: scaling recipes up and down without the compounding error of stacked cup measures.
- International cooks: bridging US-cup recipes and metric-kitchen scales in both directions.
Accuracy & limitations
These are averages, not lab measurements: how you fill the cup moves the number. Spoon flour into the cup and level it — scooping straight from the bag packs up to 20% more. Brown sugar is measured packed; sifted flour weighs less than unsifted. Kosher salt varies by brand crystal size (Diamond Crystal ~137 g/cup, Morton ~288 g/cup); 144 g is a middle value. For anything where grams matter most — bread, macarons, espresso — weigh directly and treat the chart as the bridge, not the destination.

How many grams are in a cup of flour?
One US cup of all-purpose flour weighs about 120 grams when spooned and leveled. Bread flour runs ~127 g, cake flour ~114 g, whole wheat ~113 g. Scooping from the bag can pack in 140+ g — the classic cause of dense, dry baked goods.
How many grams are in a cup of sugar?
One US cup of granulated sugar is 200 grams; packed brown sugar is ~220 g; powdered (confectioners’) sugar is ~120 g because it is mostly air.
How many grams are in a cup of butter?
One US cup of butter is 227 grams — exactly two US sticks (one stick = 113 g = 8 tbsp). This is one of the most stable conversions in the chart.
Is a US cup the same as a metric cup?
No. A US cup is 236.6 ml; a metric cup is 250 ml — about 6% larger. If a recipe from outside the US says “cup” without specifying, assume metric and multiply this chart’s gram values by 1.057, or better, use the recipe’s own weights.
Why do professional recipes use grams instead of cups?
Volume lies: the same cup of flour can weigh anywhere from ~110 g to ~150 g depending on packing, humidity, and brand. Weight is exact and scales perfectly — double the grams, double the recipe, zero compounding error. Cups are fine for soups; grams win for baking.
