Half a cup of butter equals exactly one stick of American butter, or 8 tablespoons, weighing 4 ounces (113 grams). If you're holding a standard package of North American butter, one full stick is precisely what you need when a recipe calls for this amount. Getting this measurement wrong can throw off the moisture balance in your cookies, cakes, and pastry doughs, turning a flaky crust into a dense disaster.
Knowing your measurements matters because butter behaves differently depending on its physical state and regional packaging. Whether you're cutting cold fat into flour for pie dough or softening blocks for creaming sugar, understanding the exact conversion saves your recipes from guesswork.
How Much 1/2 Cup Butter Equals in Sticks, Tablespoons, and Weight
Standardizing your kitchen measurements starts with breaking down how half a cup translates across different units.
- Sticks: Exactly 1 stick of butter (in the United States).
- Tablespoons: Exactly 8 tablespoons.
- Teaspoons: Exactly 24 teaspoons.
- Ounces: 4 ounces by weight.
- Grams: Approximately 113 grams.
- Milliliters (Liquid Volume): Roughly 118 milliliters if melted.
For everyday cooking, most people rely on the wrapper markings on American butter sticks. Each stick has tablespoon markers printed along the side, making it easy to slice off eight tablespoons without dragging out a measuring cup.

Regional Differences in Butter Packaging
If you live outside North America, or if you're using imported European butter, stick wrappers might not match your expectations.
- United Kingdom and Australia: Butter is typically sold in large blocks measured by weight (usually 250g or 500g) rather than pre-divided sticks. You'll need a kitchen scale to weigh out 113 grams.
- European-Style Butter: Even when sold in North American-style sticks, European butter often has a higher fat content (around 82% to 85% fat compared to the standard 80%) and less water. While 1/2 cup still equals one stick and 113 grams, the extra fat changes how your baked goods spread and crisp up in the oven.
Measuring Butter by State: Cold, Softened, and Melted
Measuring butter accurately depends heavily on its temperature and form. Dipping a dry measuring cup into a tub of spreadable butter or scooping softened blocks introduces air pockets that alter your final amounts.
Cold Butter for Pastry
Recipes like pie crusts, biscuits, and scones require cold butter to create steam pockets that yield flaky layers.
- Cut your stick into small cubes using the tablespoon markings as a guide.
- Toss the cold cubes directly into your dry ingredients before blending.
- Avoid packing cold chunks into a measuring cup, as empty spaces between the cubes will leave you short on actual fat.
Softened Butter for Baking
Room-temperature butter is essential for creaming with sugar, which incorporates air to make cakes light and cookies chewy.
- Let your butter sit on the counter for 30 to 45 minutes until it yields slightly to gentle thumb pressure.
- If you are using a measuring cup rather than a whole stick, press the softened butter firmly into the cup to eliminate air pockets, then level it off flat with a butter knife.
Melted Butter
When a recipe calls for melted butter—such as for brownies, quick breads, or certain sauces—measure the butter after it melts rather than before. Melting butter releases trapped air and water vapor, changing its total volume. One stick melted down will still weigh 113 grams, but the liquid volume might measure slightly less than a full half-cup until it cools or settles.
Common Kitchen Mistakes When Measuring Butter
Even experienced home cooks can stumble when converting butter measurements on the fly. Avoiding these pitfalls keeps your baking consistent.
- Mistaking volume for weight across different ingredients: A half cup of flour weighs much less than a half cup of butter because of density. Never use liquid measuring cups for dry ingredients or vice versa.
- Eyeballing uneven cuts: Cutting a stick in half visually without checking the tablespoon markers often leaves one side too heavy. Always use the printed guidelines on the wrapper.
- Using whipped or spreadable butter: Whipped butter has air beaten into it, meaning a half cup of whipped butter contains significantly less actual fat and weight than a standard stick. Check out the USDA FoodData Central for detailed nutritional breakdowns of standard dairy products.
Frequently Asked Questions
How many sticks of butter make a full cup?
Two full sticks of butter equal one cup. Therefore, half a cup is equal to one single stick.
Can I substitute margarine for butter when a recipe calls for 1/2 cup?
Yes, stick margarine can be swapped 1:1 for butter in most baking recipes. However, keep in mind that margarine contains more water and less fat, which can result in flatter cookies and less flavorful pastries. Avoid tub margarines, as their high water and oil content will ruin structural baking recipes.
What is the easiest way to soften butter quickly?
If you forgot to take your butter out of the fridge ahead of time, cut the stick into small cubes to increase its surface area, which lets it warm up to room temperature in about 10 minutes. Alternatively, fill a tall glass with hot water, empty it, and invert the warm glass directly over the stick of butter on a plate to trap the heat.
How do I measure 1/2 cup of butter if I only have a block without wrapper lines?
The most accurate method is using a digital kitchen scale to measure out 113 grams (or 4 ounces). If you don't have a scale, you can use the water displacement method: fill a liquid measuring cup with 1/2 cup of water, drop pieces of butter in until the water level rises to the 1-cup mark, and drain the water.
