Use this cooking conversion chart to move between cups, tablespoons, fluid ounces, grams, and milliliters with less guesswork. It includes quick volume tables, ingredient-specific weight estimates, a conversion workflow, and a checklist for scaling recipes or following international instructions.
Overview
Cooking measurements fall into two useful categories: volume and weight. Cups, tablespoons, teaspoons, fluid ounces, and milliliters measure volume. Grams and ounces by weight measure mass. These systems are related, but they are not interchangeable without considering the ingredient.
For example, 1 cup of water weighs about 240 grams, while 1 cup of flour is closer to 120 grams. The cup is the same size, but the ingredients have different densities. This is why a general “cups to grams” answer cannot be exact for every food.
The charts below use common United States recipe conventions: 1 cup is approximately 240 milliliters, 1 tablespoon is approximately 15 milliliters, and 1 teaspoon is approximately 5 milliliters. For the most consistent baking results, use the recipe’s stated measurement system and weigh ingredients when a weight is provided.
Quick volume conversion chart
| Measurement | Equivalent | Approximate metric volume |
|---|---|---|
| 1 teaspoon | 1/3 tablespoon | 5 ml |
| 1 tablespoon | 3 teaspoons | 15 ml |
| 1/4 cup | 4 tablespoons | 60 ml |
| 1/3 cup | 5 tablespoons + 1 teaspoon | 80 ml |
| 1/2 cup | 8 tablespoons | 120 ml |
| 2/3 cup | 10 tablespoons + 2 teaspoons | 160 ml |
| 3/4 cup | 12 tablespoons | 180 ml |
| 1 cup | 16 tablespoons | 240 ml |
| 1 pint | 2 cups | 480 ml |
| 1 quart | 4 cups | about 950 ml |
| 1 gallon | 4 quarts or 16 cups | about 3.8 liters |
For a more detailed reference, keep the cooking conversion chart for cups, ounces, tablespoons, and grams available with your other kitchen notes.
Liquid volume conversions
| US volume | Fluid ounces | Milliliters |
|---|---|---|
| 1 teaspoon | about 0.17 fl oz | 5 ml |
| 1 tablespoon | about 0.5 fl oz | 15 ml |
| 1/4 cup | 2 fl oz | 60 ml |
| 1/2 cup | 4 fl oz | 120 ml |
| 1 cup | 8 fl oz | 240 ml |
| 2 cups | 16 fl oz | 480 ml |
| 1 liter | about 33.8 fl oz | 1,000 ml |
A fluid ounce measures liquid volume; a weight ounce measures mass. Eight fluid ounces of oil, milk, or syrup may not weigh the same as 8 ounces by weight. Check the label or recipe wording before converting.
Common ingredient weights
These are practical approximations for a level US cup. Packing, grinding, sifting, moisture, and the way an ingredient is filled can change the result.
| Ingredient | 1 cup approximately | 1/2 cup approximately |
|---|---|---|
| All-purpose flour, spooned and leveled | 120 g | 60 g |
| Granulated sugar | 200 g | 100 g |
| Light brown sugar, packed | 215–220 g | 108–110 g |
| Butter | 227 g | 113–114 g |
| Rolled oats | about 90 g | about 45 g |
| Uncooked white rice | about 185 g | about 93 g |
| Water | about 240 g | about 120 g |
| Honey | about 340 g | about 170 g |
| Peanut butter | about 255 g | about 128 g |
Checklist by scenario
When a recipe gives cups but your scale uses grams
- Identify the ingredient before choosing a grams conversion.
- Check whether the recipe says packed, sifted, heaped, or level.
- Use the ingredient chart as an estimate, not as a universal rule.
- Place the bowl on the scale, tare it to zero, and add the ingredient gradually.
- Keep the same measurement method for every batch so the result is repeatable.
For flour, spoon it into a dry measuring cup and level it if you are measuring by volume. Do not compress it unless the recipe specifically calls for packed flour. Weighing is generally easier when a recipe provides a tested gram amount.
When a recipe uses grams but you need cups
- Confirm the ingredient and its reference weight per cup.
- Divide the recipe’s grams by the grams per cup.
- Convert the decimal into a practical fraction or combination of cups, tablespoons, and teaspoons.
- Use a scale instead if the amount is small or the recipe is sensitive, such as bread, pastry, or meringue.
For example, 240 grams of all-purpose flour is approximately 2 cups when using 120 grams per cup. That same 240 grams is not automatically 2 cups of sugar or rice.
When scaling a recipe
- Multiply every ingredient by the same factor. Doubling a recipe means multiplying each amount by 2.
- Convert awkward totals before measuring. For example, 10 tablespoons equals 2/3 cup plus 2 teaspoons.
- Reconsider pan size, cooking time, and liquid evaporation. Ingredient conversion alone does not guarantee the original result.
- Keep salt, spices, yeast, and leaveners precise; taste and adjust savory seasonings where appropriate.
Pan geometry matters especially in baking. If you change the pan as well as the quantity, use the cake pan conversion chart to review depth and baking-time adjustments.
When following an international recipe
First determine whether “ounce” means fluid ounce or weight ounce, and whether “cup” refers to a US cup, a metric cup, or another local standard. A metric cup is commonly treated as 250 ml, while a US recipe cup is commonly treated as about 240 ml. Small differences may not matter in a soup or stew, but they can matter in baking. If the recipe includes grams, use those measurements rather than translating them into cups.
What to double-check
- Ingredient form: chopped nuts, sliced vegetables, and whole grains occupy space differently than their ground or cooked versions.
- Packed versus loose: brown sugar is usually packed; flour is usually spooned and leveled unless stated otherwise.
- Dry versus liquid tools: dry measuring cups are filled and leveled, while liquid measuring jugs allow space for the liquid surface to be read at eye level.
- Temperature and equipment: conversions do not replace cooking judgment. Oven performance, pan material, and batch size can affect timing.
- Rounding: round liquid amounts to a useful milliliter measurement, but avoid aggressive rounding for yeast, salt, baking powder, or small quantities in baking.
For ingredient swaps that change density or moisture, consult the ingredient substitution guide rather than applying a direct cup-for-cup assumption.
Common mistakes
Confusing fluid ounces with ounces by weight: “8 ounces” on a recipe may need context. A measuring cup marked in fluid ounces is measuring volume, not the mass shown by a kitchen scale.
Treating every cup as the same weight: The correct grams conversion depends on the ingredient. Flour, sugar, butter, and rice each have different densities.
Using a liquid cup for flour: A liquid jug is difficult to level accurately for dry ingredients. Use a dry cup and level it, or weigh the ingredient.
Ignoring preparation details: “1 cup chopped onion” is not the same as “1 cup onion, chopped.” The first describes the volume after chopping; the second can describe a whole-volume measure before chopping.
Over-rounding small amounts: Replacing 1/8 teaspoon with a vague pinch may be acceptable for some herbs, but it is less reliable for chemical leaveners or concentrated spices.
Changing several variables at once: If you convert units, double the batch, substitute ingredients, and change the pan, it becomes difficult to identify the cause of a poor result. Make one major adjustment at a time when testing a recipe.
When to revisit
Save this chart for routine recipe planning, baking, meal prep, and pantry cooking. Recheck it before a seasonal baking cycle, when buying a new scale or measuring set, or when a recipe switches between US customary and metric units. Ingredient weight references should also be reviewed periodically because published charts may use different assumptions for scooping, packing, or ingredient brands.
Before you begin, run this final checklist:
- What measurement system does the recipe use?
- Does the ingredient require a specific form, such as packed, sifted, melted, or drained?
- Am I measuring volume or weight?
- Have I separated fluid ounces from weight ounces?
- Will scaling change the pan, cooking time, or storage needs?
- Would weighing the ingredient be more dependable than estimating a volume?
Once the measurements are clear, continue with the recipe’s own visual and doneness cues. For batch cooking, pair conversions with the freezer-friendly meal planning guide; for cooked leftovers, review how to store cooked food safely.
