Frequently asked questions

Everything people ask about converting between grams and cups — answered with the same standard weights the converter uses.

How many grams are in a cup?

It depends entirely on the ingredient, because a cup measures volume, not weight. A cup of all-purpose flour is 120 g, a cup of granulated sugar is 200 g, a cup of honey is 340 g and a cup of cocoa powder is only 85 g. There is no single grams-per-cup number — always convert by ingredient.

Is 250 grams equal to 1 cup?

Only for ingredients that happen to weigh about 250 g per cup, like peanut butter (258 g). 250 g of flour is about 2.08 cups, 250 g of sugar is 1.25 cups, and 250 g of water is just over 1 cup (237 g per cup). Pick your ingredient above and enter 250 to get the exact answer.

How do I convert grams to cups without a scale?

Find your ingredient in the converter, enter the grams from the recipe, and read off the cup value. We also show the nearest common kitchen fraction (like 2 1/8 cups) plus tablespoons and teaspoons, so you can measure with the spoons you already own.

Why do US and metric recipes give different results?

This converter uses the US cup of 240 ml and standard published ingredient weights. A metric cup is 250 ml — about 4% larger — so for a metric recipe, add roughly 4% to the cup amounts shown here. Grams never change, which is why weighing is the safer method.

What is the difference between spooned and scooped flour?

Scooping flour straight from the bag with the measuring cup packs it down and can add 15–20% extra flour. Spooning flour into the cup and levelling it off gives the standard 120 g per cup that this chart uses — and much more reliable bakes.

Are the weights on this page exact?

They are the standard published weights used by major recipe and baking references, spooned and levelled unless a note says otherwise. Real ingredients vary a little by brand, humidity and how you fill the cup, so treat conversions as accurate to within a few grams — and weigh when a recipe is fussy.

How many grams are in 1 cup of flour?

120 g for all-purpose flour, spooned and levelled. Bread flour is a little heavier at 127 g per cup and cake flour lighter at 114 g.

How many grams are in 1 cup of sugar?

200 g for granulated sugar. Brown sugar packed into the cup is 220 g, while powdered (icing) sugar is only 120 g per cup — half the weight of granulated.

Is a cup always 240 ml?

The US cup used on this site is 240 ml (the nutrition-label standard, 236.6 ml rounded). A metric cup is 250 ml, about 4% more, so multiply cup amounts by 1.04 for metric recipes.

How many grams is half a cup of butter?

About 113 g — butter is 227 g per cup, and a US stick is exactly half a cup (113 g), which makes butter the easiest ingredient to convert.

Can I convert cups to grams for liquids the same way?

Yes. Liquids convert by density: water is 237 g per cup, milk 240 g, oil 218 g and honey a dense 340 g. The converter handles all of them.

Why does my result differ from another website?

Sites disagree mainly on flour. We use 120 g per cup for all-purpose flour (spooned & levelled), the value used by major baking references. A site using a scooped value like 125–130 g will give slightly smaller cup results.

Which ingredients does the converter cover?

Twenty-one: all-purpose, bread and cake flour; granulated, brown and powdered sugar; butter, cocoa powder, honey, rolled oats, cornstarch, uncooked rice, milk, water, vegetable oil, almond flour, peanut butter, chopped nuts, shredded cheese, sour cream and cream cheese.

Does GramsToCups work offline or store my data?

Conversions happen in your browser with a small built-in table. We don't store, send or analyse the amounts you enter.

Can I embed this converter on my recipe site?

An embeddable widget is planned as part of Pro ($9/month, coming soon). Until it launches, feel free to link to any converter or chart page — links are welcome.
