    How it works

    Three steps, no account

    Pick a conversion

    Choose cups to grams for ingredients, volume for cups and spoons, weight for ounces and pounds, or oven temperature for Celsius, Fahrenheit and gas marks.

    Enter an amount and two units

    Type your number, choose the ingredient if you are converting between cups and grams, then pick the unit to convert from and the unit to convert to. The result updates as you type.

    Read and copy the result

    The converted amount appears in large type with the full equation below it. Copy it with one click, change the number of decimal places, or swap the two units.

    Why it matters

    Measure right, cook with confidence

    A recipe from another country often uses cups where yours uses grams, or Fahrenheit where your oven shows Celsius. A wrong conversion can mean a dense cake, a dry loaf or a burnt crust.

    Volume and weight conversions between cups, spoons, milliliters and ounces use exact unit definitions. Converting a cup into grams is different, because it depends on the ingredient: a cup of flour weighs far less than a cup of honey. The converter uses typical weights per cup from baking charts and food-composition data and rounds those results, since real ingredients vary.

    Use cases

    Where a cooking converter helps

    Baking from US recipes

    Turn cups of flour, sugar and butter into grams so you can weigh them on a kitchen scale.

    Recipes from abroad

    Switch between US cups, metric cups of 250 milliliters, tablespoons, teaspoons and fluid ounces.

    Oven settings

    Convert 350 °F to Celsius or find the UK gas mark that matches a temperature in a recipe.

    Scaling recipes

    Change cups, ounces and pounds into one unit first, then double or halve a recipe with fewer mistakes.

    Using a kitchen scale

    See the same amount in grams, ounces, pounds and cups side by side before you start measuring.

    Under the hood

    How the conversion works

    Volume units such as cups, spoons and milliliters, and weight units such as grams and ounces, are each defined by their exact size relative to a base unit, so every pair converts consistently. Cups to grams adds one step: the volume is multiplied by a typical density for the ingredient you pick. Oven temperatures use the Celsius and Fahrenheit formulas, and gas marks are read from a standard chart of UK gas marks. Everything is calculated locally with standard JavaScript numbers and formatted for your language.

    Questions

    Frequently asked questions

    Basics
    Is this cooking converter really free?
    Yes. The converter is completely free, with no limit on how many conversions you make. There is no paid tier and no feature locked behind a payment.
    Do I need an account to use it?
    No. There is no sign-up, no login and no account of any kind. Open the page, enter an amount and read the result.
    Are my numbers stored or sent anywhere?
    No. Everything happens inside your own browser. The values you type are never uploaded, stored or transmitted to any server. After the page has loaded, the converter works the same even without an internet connection.
    How accurate are the cups-to-grams results?
    They are good kitchen estimates, not laboratory values. Each ingredient uses a typical weight per US cup taken from baking charts and food-composition data, and results are shown with three significant digits. Real flour, sugar or butter can weigh a little more or less depending on brand, humidity and how the cup is filled.
    Options & usage
    How do I convert cups to grams?
    Open the Cups to grams tab, choose your ingredient, type the number of cups and pick grams as the target unit. The result appears immediately. You can also convert the other way, from grams to cups, tablespoons or teaspoons.
    Which ingredients are included?
    More than 100 common ingredients in nine groups: flours and starches, grains and rice, sugars and sweeteners (including xylitol and erythritol), fats and oils, dairy and liquids, baking basics, nuts and seeds, spices and salt, and fruit and other. Type in the search box above the ingredient list to find one quickly.
    Why does a cup of flour weigh less than a cup of sugar?
    A cup measures volume, not weight. Flour is light and airy, while granulated sugar and honey are denser, so the same cup holds a different weight of each. That is why a conversion between cups and grams has to depend on the ingredient.
    Which cup does the converter use?
    By default it uses the US customary cup of 236.588 milliliters. A metric cup of 250 milliliters is also available, as used in recipes from Australia, New Zealand, Canada and elsewhere. The US legal cup of 240 milliliters used on nutrition labels is not a separate option.
    What is a UK gas mark?
    A gas mark is a number on many British gas ovens that stands for a temperature. For example, gas mark 4 is 180 °C or 350 °F. The converter uses the common chart from gas mark ¼ to 9, which some manufacturers adjust slightly.
    Privacy & technical
    Can I enter decimals with a comma?
    Yes. You can type 1.5 or 1,5. If a number contains both a dot and a comma, the one that comes last is treated as the decimal separator. Results are displayed with the decimal separator of the page language.
    How are the conversions calculated?
    Volume and weight values are converted to a base unit with exact factors and then to the target unit; cups to grams multiplies the volume by the ingredient density. By default, ingredient results use three significant digits, oven temperatures are rounded to whole degrees and other results show up to ten significant digits. The Decimal places option rounds what you see and copy.
    Can I convert xylitol or erythritol, and do they weigh the same as sugar?
    Yes, both are in the list. The converter uses about 192 g per US cup for xylitol and about 200 g for granular erythritol, close to the 198 g it uses for granulated sugar. These figures come from product labels and home measurements and vary by brand and grind, so treat them as estimates and check the package. The converter only changes units; for how much sweetener to use in place of sugar, follow your recipe.
