Cooking Converter: Convert Recipe Measurements Easily
Nothing ruins a recipe faster than using the wrong measurements. Whether you're following a recipe from another country that uses metric instead of imperial, or you need to scale a recipe up or down, our Cooking Converter handles all common kitchen conversions. Convert between cups, tablespoons, teaspoons, milliliters, liters, ounces, grams, and pounds for both liquid and dry ingredients. Use our Cooking Converter to estimate your costs.
Common Kitchen Conversions
Knowing basic kitchen conversions saves time and prevents mistakes. One cup equals 16 tablespoons, 48 teaspoons, or 237 milliliters. One tablespoon equals 3 teaspoons or 15 milliliters. One fluid ounce equals 2 tablespoons or 30 milliliters. One pound equals 16 ounces or 454 grams.
Volume measurements are straightforward for liquids, but dry ingredients vary by density. One cup of all-purpose flour weighs approximately 120 grams, while one cup of granulated sugar weighs 200 grams. Our converter includes ingredient-specific density adjustments for accurate baking.
Using the Cooking Converter
Select the ingredient type (flour, sugar, butter, water, milk, oil, or generic), enter the amount, and choose the units you are converting from and to. The converter handles volume-to-volume, volume-to-weight, and weight-to-weight conversions with ingredient-specific densities.
For scaling recipes, enter the original ingredient amounts and the desired number of servings. The calculator adjusts all quantities proportionally. This is especially useful when halving or doubling recipes.
Ingredient Density Reference
Flour
All-purpose flour: 120g per cup. Whole wheat flour: 130g per cup. Bread flour: 127g per cup. Cake flour: 114g per cup. Scoop and level for accurate measurement — do not pack flour into the cup.
Sugar
Granulated sugar: 200g per cup. Brown sugar (packed): 220g per cup. Powdered sugar: 120g per cup. Brown sugar should be firmly packed into the measuring cup for accurate results.
Butter
Butter: 227g per cup, 113g per stick, 14g per tablespoon. Most butter sticks have measurement markings on the wrapper for easy cutting.
Liquids
Water: 237g per cup. Milk: 244g per cup. Vegetable oil: 218g per cup. Honey: 340g per cup. Liquid ingredients should be measured in liquid measuring cups with a spout.
Metric vs Imperial in Recipes
Recipes from the United States use imperial units (cups, teaspoons, ounces). Most other countries use metric (grams, milliliters). Australian recipes use metric but define 1 cup as 250ml (versus 237ml in the US). British recipes often use imperial weights (ounces, pounds) but may also include metric equivalents.
When converting between systems, use weight measurements (grams, ounces) for the most accurate results. Volume conversions between cups and milliliters are approximate and can lead to errors in baking recipes that require precise ratios.
Baking Precision Tips
- Weigh ingredients: A kitchen scale is more accurate than measuring cups, especially for flour which compresses easily
- Spoon and level: Spoon flour into your measuring cup and level with a knife — never scoop directly with the cup
- Room temperature: Many baking recipes assume ingredients like butter and eggs are at room temperature
- Altitude adjustments: High altitude (3,000+ feet) may require reducing sugar and increasing liquid in baking recipes
- Ingredient substitutions: Different brands of flour, butter, and other ingredients can vary in density — adjust as needed
Scaling a Recipe Correctly
The scaling feature multiplies every ingredient by the same factor, which works for most recipes but has two traps. First, liquids and solids do not always behave linearly in practical cooking: a doubled soup may need a longer simmer to reduce properly, and yeast or baking powder in a doubled bread recipe is not always exactly double because proofing times shift. Second, scaling a recipe measured in volume and re-measuring in volume compounds rounding errors — halving a recipe that calls for a third of a cup of oil means measuring 2.67 tablespoons, which few cooks can do accurately.
Convert the problem into weight first. A recipe calling for 2 cups of all-purpose flour uses about 240 grams (120g per cup), so a half batch needs exactly 120 grams on a scale. The same principle applies to butter: a half batch of a recipe using 227 grams (one cup) needs 113.5 grams, precisely one stick. Working in grams instead of cups keeps the ratios exact across any scale factor and sidesteps the rounding that volume measurement forces into every partial quantity.
- Scale by grams and ounces rather than cups for any recipe factor that produces a fraction of a cup.
- Recalculate leavening (baking soda, baking powder, yeast) as a weighed percentage of the flour rather than a straight multiplication when the scale factor is 1.5 or higher.
- Write down the converted quantities before you start, because mid-recipe conversions are where most scaling mistakes happen.
