How many grams is 1 cup of flour?

125 g of all-purpose flour spooned into the cup and levelled off, which is what most modern recipes mean by a cup of flour. Scooping the cup through the bag packs it to 140 g. Both are real published conventions and the 15 g between them shows in the finished loaf, which is why this tool lists them separately instead of averaging them into one number nobody uses.

How many grams is 1/2 cup?

It depends entirely on what is in the cup, because a cup measures volume and a gram measures mass. Half a cup of spooned all-purpose flour is 62.5 g, half a cup of granulated sugar is 100 g, and half a cup of butter is 113.5 g. Pick the ingredient above and the answer changes with it; the density used is printed under every result with its source.

How many grams is 1 1/2 cups?

187.5 g of all-purpose flour spooned into the cup, 210 g scooped, 300 g of granulated sugar and 340.5 g of butter. The amount field reads 1 1/2, 1½ and 1.5 as one and a half. Typed as 11/2 with the space lost, it reads eleven halves, which is 5.5 cups, so keep the space.

How many grams is 2 cups of flour?

250 g spooned, or 280 g scooped.

Why do other sites give a different number for a cup of flour?

Because they are quoting different conventions without saying so. 120, 125, 128 and 140 g all appear on the first page of results for the same question, and each is a real published figure for a particular way of filling the cup. This page uses 125 g for spooned and 140 g for scooped, says which one each column rests on, and prints the density beside every result so there is no hidden average.

Is a metric cup different?

Yes. A metric cup is 250 mL against the US cup's 236.588 mL, so a metric cup of spooned all-purpose flour holds 132.1 g rather than 125 g. There is a switch for it above, and it moves the tablespoon to 15 mL and the teaspoon to 5 mL at the same time. Everything on this page is the US cup.

Which flour should I pick?

All-purpose spooned is the default and the safest reading of an unqualified recipe. The list also has bread flour at 127 g a cup, cake flour at 114 g, pastry and whole wheat at 120 g, self-rising at 125 g, almond at 96 g, coconut at 112 g and rye at 102 g, each with the source of its figure.

Cups to Grams

Convert cups to grams by ingredient, starting on 1 cup of all-purpose flour spooned into the cup, which is 125 g. Flour is where the method matters most. A cup scooped straight through the bag packs to 140 g, 12 percent more, so both conventions are separate entries here, and the table below gives every common cup amount under each of them, beside granulated sugar and butter.

There is no single answer to “how many grams in a cup”. A cup of cocoa powder is 85 g, a cup of honey is 340 g, and both are correct, which is why the ingredient is a required choice here rather than an optional refinement. Accuracy. Cups measure volume and grams measure mass, so the answer depends on the ingredient; the density used is shown beside every result with its source. Flour differs by about 12 percent between spooned and scooped, and both are listed.

Cups to grams: flour, sugar and butter

Computed with the tool's own figures, per US cup of 236.588 mL: all-purpose flour spooned and levelled at 125 g a cup, the same flour scooped through the bag at 140 g, and granulated sugar at 200 g and butter at 227 g, both from USDA FoodData Central. Scooped flour is 12 percent heavier than spooned throughout, so a recipe written for one and measured by the other is out by that much before anything else goes wrong.
