Recipe Measurement Converter

Convert cups, spoons, ounces, grams, milliliters, and liters with ingredient-aware estimates.

Use decimals or recipe fractions such as 1 1/2 or 3/4.

Kitchen note: Volume-to-weight conversions are estimates. Ingredients compress, settle, and vary by brand, so weigh ingredients when baking needs precision.

Calculation Steps

    Why Recipe Conversions Need Ingredients

    A cup measures volume, while grams and ounces measure weight. The ingredient determines the bridge between them.

    Volume vs. weight

    Cups, tablespoons, teaspoons, fluid ounces, milliliters, and liters measure space. Grams, kilograms, ounces, and pounds measure mass.

    Ingredient density

    One cup of honey weighs much more than one cup of flour. The calculator uses a grams-per-cup assumption for the selected ingredient.

    Baking precision

    Flour, cocoa, shredded cheese, and similar ingredients can change weight depending on how they are scooped or packed. For repeatable baking, use a scale.

    Recipe Conversion Examples

    Common conversions when adapting American recipes to metric kitchens.

    Flour for a cake recipe

    1 1/2 US cups of all-purpose flour is about 180 g using 120 g per cup.

    Butter in a cookie recipe

    1/2 US cup of butter is about 114 g, close to one US stick.

    Sugar by weight

    200 g granulated sugar is about 1 US cup using 200 g per cup.

    Recipe Measurement FAQ

    Common questions about cups, grams, ingredient density, and practical recipe conversion.

    Why do I need to choose an ingredient?

    Cups and spoons measure volume, while grams and ounces measure weight. Different ingredients have different densities, so the selected ingredient controls volume-to-weight conversions.

    Is one cup always 240 ml?

    This calculator uses the US cup commonly found in American recipes: about 236.59 ml. Metric cup references may use 250 ml, so check the recipe source when precision matters.

    How accurate are cups to grams conversions?

    They are practical estimates based on common grams-per-cup values. Flour, cocoa powder, shredded cheese, and similar ingredients can vary depending on packing, scooping, brand, and humidity.

    Can I enter recipe fractions?

    Yes. You can enter values like 1 1/2, 3/4, 2-1/4, decimals, or common unicode fractions such as 1/2.

    When should I use the custom cup weight?

    Use custom grams per cup when your ingredient is not listed, when a package gives a specific cup weight, or when you weighed one level cup yourself.
