Cooking Converter: Cups, Grams, Tablespoons

Convert between cooking measurements with ingredient-specific accuracy. Select your ingredient, enter the amount, and get precise conversions between cups, tablespoons, teaspoons, grams, ounces, and milliliters. For all unit categories see our Unit Converter, or convert liquid volumes with the Volume Converter.

Ingredient Density Reference

How it works

This converter uses verified ingredient density data to translate between volume and weight measurements. When you convert cups to grams, the result depends on the ingredient: one cup of flour is 125 grams, but one cup of honey is 340 grams because honey is much denser. Volume-to-volume conversions (e.g., US cups to milliliters) are ingredient-independent since they are pure volume ratios.

Select your ingredient, enter the amount, and choose your source and target units. The converter first translates the input to grams using the ingredient's density, then converts grams to the target unit. All density values come from standard culinary references and USDA data.

How Cooking Conversion Works

Cooking conversion is more complex than standard unit conversion because the relationship between volume and weight depends on the ingredient. One cup of flour (125 grams) weighs far less than one cup of honey (340 grams) because their densities differ. Volume-to-volume conversions (cups to milliliters) are straightforward: 1 US cup equals 237 milliliters. But volume-to-weight conversions (cups to grams) require knowing the specific ingredient. This converter uses verified density data for common ingredients to provide accurate weight equivalents for any volume measurement.

Common Cooking Conversions

The most frequently needed cooking conversions are cups to grams (especially for flour, sugar, and butter), tablespoons to milliliters, teaspoons to grams (for salt, baking powder, spices), and sticks of butter to grams. Key reference values: 1 US cup of all-purpose flour is 125 grams, 1 cup of granulated sugar is 200 grams, 1 cup of butter is 227 grams (2 sticks), and 1 tablespoon is approximately 15 milliliters. These conversions are essential when following recipes from different countries or scaling recipes up or down.

When You Need Cooking Conversion

Cooking conversion is essential when following American recipes (which use cups, tablespoons, and teaspoons) outside the US where kitchen scales and milliliters are standard. It is equally important when European or Asian recipes specify gram weights and a US home cook has only measuring cups. Professional bakers strongly prefer weight measurements for consistency because volume measures vary with how densely an ingredient is packed. Converting between regional tablespoon sizes is also necessary: a US tablespoon is 14.8 ml, an Australian tablespoon is 20 ml, and a UK tablespoon is 17.7 ml.

Measuring by Weight vs. Volume

Professional bakers and pastry chefs worldwide measure ingredients by weight (grams) rather than volume (cups) because weight is far more consistent and reproducible. A cup of flour can weigh anywhere from 120 to 150 grams depending on whether it is sifted, spooned, or scooped. Sugar is more consistent but still varies. Butter, being a solid, can be measured accurately either way. Liquids like water and milk have a density close to 1 gram per milliliter, so volume and weight are nearly interchangeable. For the most reliable baking results, invest in a kitchen scale that reads in grams.

Tips for Accurate Cooking Conversion

When measuring flour by volume, spoon it into the cup and level with a straight edge — do not scoop directly from the bag, which compacts the flour and can add 20 percent more. For brown sugar, pack it firmly into the cup as recipes assume packed measurement. Butter wrappers in the US have tablespoon markings; 1 stick equals 113 grams or 8 tablespoons. When halving or doubling recipes, convert to grams first, then scale, then convert back if needed. This avoids the rounding errors that accumulate when scaling fractional cups and teaspoons.

Practical Examples

A recipe calling for 2 cups of all-purpose flour needs 250 grams. Three tablespoons of butter equals 42.6 grams. One teaspoon of salt is 5.7 grams. A European recipe asking for 150 grams of sugar needs 3/4 US cup. Two cups of milk (488 grams) is close to 500 milliliters (the slight difference is due to milk being denser than water). A tablespoon of honey (21 grams) weighs more than a tablespoon of oil (13.6 grams) because honey is significantly denser.

FAQ

How many grams are in one cup of flour?
One US cup of all-purpose flour weighs approximately 125 grams when measured using the spoon-and-level method. If you scoop the cup directly into the flour bag, it can weigh up to 150 grams due to compaction. For accuracy, spoon flour into the measuring cup and level the top with a straight edge. Bread flour is slightly heavier at about 130 grams per cup.
How many grams are in a tablespoon?
It depends on the ingredient because a tablespoon measures volume, not weight. A US tablespoon of water weighs about 14.8 grams, sugar about 12.5 grams, flour about 8 grams, butter about 14.2 grams, and honey about 21 grams. The US tablespoon is 14.787 ml. The Australian tablespoon is 20 ml (about 33 percent larger), which matters when following Australian recipes.
Why do cups-to-grams conversions vary by ingredient?
Because different ingredients have different densities. A cup measures volume (about 237 ml for a US cup), but grams measure weight. Dense ingredients like honey (340 g per cup) weigh much more than light ingredients like oats (90 g per cup) despite filling the same cup volume. This is why professional bakers prefer weighing ingredients in grams — it eliminates the density variable entirely.
How much is a stick of butter in grams?
One US stick of butter is exactly 113 grams (4 ounces or 1/2 cup or 8 tablespoons). Two sticks equal one cup (227 grams). Most US butter packaging has tablespoon markings printed on the wrapper for easy measuring. In Europe, butter is typically sold in 250-gram blocks. To convert: 1 European block = 2.21 US sticks.
What is the difference between US and UK tablespoon sizes?
A US tablespoon is 14.787 ml (rounded to 15 ml). A traditional UK tablespoon is 17.758 ml, though many modern UK cookbooks use the 15 ml metric standard. An Australian tablespoon is 20 ml — the largest of the three. This means an Australian recipe calling for 2 tablespoons of sugar uses 40 ml versus 30 ml in a US recipe. Always check which system your recipe uses.
How do I convert European recipes from grams to cups?
Divide the gram amount by the grams-per-cup value for each ingredient. For flour: 250 g / 125 g per cup = 2 cups. For sugar: 200 g / 200 g per cup = 1 cup. For butter: 100 g / 227 g per cup = about 7 tablespoons. Each ingredient has its own conversion rate, so there is no single grams-to-cups multiplier. For best accuracy, buy a kitchen scale and measure in grams directly.
How do I measure brown sugar — packed or loose?
Unless a recipe specifies otherwise, brown sugar is always packed into the measuring cup. Press it firmly into the cup until level with the top. One packed US cup of brown sugar weighs about 220 grams (light brown) to 230 grams (dark brown). Loosely scooped brown sugar weighs significantly less — about 145 grams per cup — and will result in an under-sweetened recipe.
What is the difference between liquid and dry measuring cups?
Liquid measuring cups (usually glass or clear plastic with a spout) and dry measuring cups (usually metal or plastic, meant to be leveled) hold the same volume — one US cup is 237 ml in both. The difference is design: liquid cups have extra space above the line so you can fill without spilling, while dry cups are meant to be filled and leveled. Using a liquid cup for flour or a dry cup for milk introduces small measurement errors.
How do I convert teaspoons of baking powder to grams?
One US teaspoon of baking powder weighs approximately 4.6 grams. Common recipe amounts: 1/2 tsp = 2.3 g, 1 tsp = 4.6 g, 1.5 tsp = 6.9 g, 2 tsp = 9.2 g. Baking powder is a leavening agent where precise measurement matters — too much creates a bitter taste and too little prevents rising. For baking soda, 1 teaspoon weighs about 4.6 grams as well.
How do I scale a recipe up or down accurately?
First convert all measurements to grams using ingredient-specific conversions. Then multiply or divide each amount by your scaling factor. Finally, convert back to cups or tablespoons if needed. For example, to halve a recipe calling for 2 cups of flour (250 g): 250 / 2 = 125 g = 1 cup. Scaling in grams avoids the awkward fractions that arise when halving "3/4 cup" or "1/3 tablespoon" in volume measurements.
How many teaspoons are in a tablespoon?
There are exactly 3 teaspoons in 1 tablespoon in all measurement systems. A US tablespoon is 14.787 ml, and a US teaspoon is 4.929 ml (14.787 / 3 = 4.929). This ratio holds for US, UK, and metric tablespoons — the individual sizes differ between systems, but the 3:1 ratio is universal. There are also 48 teaspoons in 1 US cup (16 tablespoons x 3).
Should I measure flour by weight or volume?
By weight (grams) whenever possible. A cup of flour can vary from 120 to 150 grams depending on the measuring method, brand, and humidity. This 25 percent variation significantly affects baked goods. Professional pastry chefs and bakeries worldwide measure flour by weight. If you must use cups, use the spoon-and-level method: fluff the flour, spoon it into the cup, and level with a knife edge.
How do I convert milliliters to cups for cooking?
Divide milliliters by 236.588 to get US cups, or by 250 for metric cups. Common conversions: 100 ml = 0.42 US cups, 200 ml = 0.85 US cups (about 7/8 cup), 250 ml = 1.06 US cups (1 metric cup), 500 ml = 2.11 US cups, 1,000 ml (1 liter) = 4.23 US cups. For metric cooking, 250 ml is conveniently equal to exactly 1 metric cup.
What is the difference between sifted and unsifted flour measurements?
One US cup of sifted flour weighs about 115 grams, while one cup of unsifted flour weighs about 125-130 grams. Sifting introduces air and reduces density. The phrase "1 cup sifted flour" means sift first, then measure. "1 cup flour, sifted" means measure first, then sift. This distinction can change the amount by 10-15 percent and noticeably affect cake texture.
How do I convert between metric and US cooking measurements for liquids?
For liquids, volume-to-volume conversion is straightforward since density does not vary much: 1 US cup = 237 ml, 1 US tablespoon = 15 ml, 1 US teaspoon = 5 ml (these are rounded metric equivalents). For practical cooking, treat 1 cup as 240 ml and 1 tablespoon as 15 ml. The small rounding error (about 1 percent) is negligible in cooking though it could matter in precise baking.
What is a "pinch" and other informal cooking measurements?
A pinch is the amount you can hold between your thumb and index finger, typically about 1/16 of a teaspoon or roughly 0.3 grams of salt. A dash is about 1/8 teaspoon (0.6 ml). A smidgen is 1/32 teaspoon. These imprecise measurements are used for seasonings where exact amounts matter less than personal taste. Some measuring spoon sets include tiny "pinch" and "dash" spoons for consistency.
