Butter Weight in Grams per Cup: Why a Kitchen Scale Beats Measuring Cups

How Many Grams of Butter Are in a Cup?

One US cup of butter weighs 226 grams, or 8 ounces. This is the standard weight for a cup of butter in American recipes, and it matches the weight of two standard sticks of butter. If you see a recipe that calls for butter in grams, 1 cup equals 226 g, and ½ cup equals 113 g.

Butter is sold in sticks and blocks that are marked with cup and tablespoon lines, so you can cut off what you need without a scale. However, those markings are only accurate if the butter is cold and firm. Once butter softens or melts, its volume changes, and cup measurements become unreliable.

A kitchen scale removes all guesswork. Instead of packing butter into a measuring cup and trying to read the lines, you simply place a bowl on the scale, zero it, and add butter until the display reads the target grams. This is especially helpful for European recipes, which list butter in grams rather than cups.

Grams and Ounces for Common Butter Amounts

Recipes in the United States often list butter in cups and sticks, while recipes from Europe and Australia use grams. Knowing the equivalents helps you move between systems without converting on the fly. The table below covers the amounts you are most likely to see in baking.

One stick of butter is 113 grams, which is 4 ounces or ½ cup. A half stick is 56.7 grams, about 2 ounces or ¼ cup. If a recipe asks for ¾ cup of butter, that is 170 grams or 6 ounces. These numbers are consistent because butter is denser than water, so a cup of butter weighs more than a cup of water (which is 240 grams).

When you weigh butter, use grams for precision. Ounces are fine for rough amounts, but grams allow you to measure to the nearest gram, which matters in recipes that are sensitive to fat content, such as croissants, pie dough, and macarons.

Why Weighing Butter Is More Accurate Than Using Cups

Measuring butter by volume is imprecise because butter is not a uniform solid. A cold stick cut along the markings is close, but if the butter is softened, it can squish into a measuring cup and trap air, giving you less butter than the recipe expects. Conversely, if you pack it firmly, you can end up with more.

A kitchen scale measures the actual fat content. This matters in baking because butter affects texture, moisture, and how dough spreads. Too little butter makes cookies dry and crumbly; too much makes them greasy and flat. Weighing eliminates the variable of how you scoop or cut.

Weighing also makes cleanup easier. You do not need to wash a measuring cup coated in butter. Place your mixing bowl on the scale, zero it, add the butter, and then add the other ingredients, zeroing between each one. This is a common technique in professional pastry kitchens and is worth adopting at home.

How to Weigh Butter With a Kitchen Scale

Start with a digital kitchen scale that measures in grams and ounces. Place a small bowl or a piece of parchment paper on the scale, then press the tare or zero button so the display reads 0. Cut butter from the stick or block and add it to the bowl until you reach the target weight.

If you are using a whole stick, the wrapper markings tell you where to cut, but you can also just weigh it. For example, if a recipe needs 150 grams, cut slightly more than one stick, weigh it, and trim. For cold butter, a sharp knife gives clean cuts; for softened butter, use a spoon to scoop it into the bowl.

For melted butter, weigh it in a liquid measuring cup or a small saucepan on the scale. Melt the butter in a microwave or on the stove, then pour it into the container on the scale. Zero the scale with the empty container first. Remember that melted butter has the same weight as solid butter, but its volume is different, so always weigh it rather than using a liquid measuring cup.

• Place a bowl or container on the scale and press tare/zero.
• Add butter in pieces until the display shows the target grams.
• For melted butter, weigh it after melting in a heat-safe container.
• Use the gram setting for the most precise measurements.

What About Salted vs. Unsalted Butter?

Salted and unsalted butter have the same weight per cup: 226 grams. The only difference is the salt content, which can affect the flavor and the chemistry of your baked goods. Salted butter contains about 1.5 to 2 percent salt, which can alter the balance of a recipe that calls for unsalted butter.

Most baking recipes specify unsalted butter so the baker controls the salt. If you only have salted butter and the recipe calls for unsalted, you can use it, but reduce the added salt in the recipe by about ¼ teaspoon per stick (113 g). Weighing does not change this substitution; it only ensures you use the right amount of butter.

Regardless of type, weigh your butter to get the correct fat content. Salted and unsalted butters have similar fat percentages (around 80 percent), so the weight is the same. The scale does not care about the salt; it just measures the butter, which is why it is a reliable tool for any recipe.

Common Questions About Butter Weights

If you do not have a scale, you can still measure butter using the markings on the wrapper. A standard US stick of butter is ½ cup, and the wrapper has lines for tablespoons, ¼ cup, and ⅓ cup. Cut along the line for the amount you need. This works best when the butter is cold, so the lines are visible and the cut is clean.

For butter that comes in a block rather than sticks, such as in Europe, check the package for weight in grams. A typical block is 250 grams, which is slightly more than 1 cup (226 g). If a recipe calls for 1 cup, weigh out 226 g from the block, or use a measuring cup as a backup.

When a recipe lists butter in cups but you want to weigh it, use the conversions in the table above. For odd amounts, like ⅔ cup, calculate: ⅔ of 226 g is about 150 g. A scale makes these conversions trivial because you just set the target weight.
