Butter Conversion Calculator

The butter conversion calculator converts any amount of butter instantly between US sticks, cups, tablespoons, teaspoons, grams, and ounces. It's the fastest way to answer the most common kitchen conversion question: 'How many tablespoons are in a stick of butter?' — and its many variations.

US butter is sold in 1-pound packages containing 4 sticks, each stick weighing 113.4 grams (4 oz / ½ cup / 8 tablespoons). This standard makes stick-based measurement convenient for American recipes, but international recipes (which measure butter by weight in grams) and older American recipes (which often specify cups or tablespoons) require conversion.

European butter is sold in blocks by weight — 125 g, 250 g, or 500 g blocks are common. European recipes specify butter in grams. The gram column in this calculator bridges the gap between European recipe weights and the stick measurements on American butter packaging.

The key conversion facts every baker should know: 1 stick = ½ cup = 8 tablespoons = 113 grams = 4 oz. Half a stick = ¼ cup = 4 tablespoons = 57 grams. A full pound of butter (4 sticks) = 2 cups = 454 grams. These numbers appear in virtually every baking recipe.

Softened versus melted butter is a separate consideration that conversion cannot address — it is a question of physical state, not quantity. Softened butter (room temperature, about 65 °F / 18 °C) is used for creaming because it traps air bubbles when beaten with sugar. Melted butter is used in quick breads and brownies where a denser, moister crumb is desired. The recipe specifies which state to use; this calculator handles only quantity conversion.

Establish the base unit: 1 US stick of butter = 113.4 grams.

All conversions go through grams: multiply the input amount by its grams-per-unit conversion factor, then divide by the target unit's grams-per-unit factor.

For cups: 1 cup = 2 sticks = 226.8 grams. For tablespoons: 1 tbsp = ⅛ stick = 14.175 grams. For teaspoons: 1 tsp = 1/24 stick = 4.725 grams. For ounces: 1 oz = 28.35 grams.

Round to meaningful precision: grams to 1 decimal place; sticks and cups to nearest ¼ (using fraction notation); tablespoons and teaspoons to 1–2 decimal places.

Key Constant

¾ cup butter: 0.75 × 226.8 = 170.1 g = 1.5 sticks = 12 tablespoons = 6 oz.

100 grams butter: 100 ÷ 113.4 = 0.88 sticks ≈ ¾ stick + 1 tsp; 100 ÷ 14.175 = 7.05 tablespoons ≈ 7 tbsp.

1/3 cup butter: 0.333 × 226.8 = 75.6 g ≈ 5 tablespoons + 1 teaspoon.

2 sticks butter: 2 × 113.4 = 226.8 g = 1 cup = 16 tablespoons = 8 oz = ½ lb.

Volumetric measuring of dry ingredients introduces substantial variance: dipping a measuring cup directly into a flour bag compacts the flour, packing up to 150 grams into a cup intended to hold 120 grams (a 25% error that produces dry, dense baked goods).

Using a digital kitchen scale and the Butter Conversion Calculator guarantees identical baker's percentages, ensuring repeatable crust, crumb, and moisture across every batch.

When scaling chemical leaveners (baking powder or soda) by more than 4×, scale leavening slightly lower (typically 75% to 85% of linear scale) to prevent dough collapse.

US stick of butter: the standard American retail unit for butter — a rectangular block of 113.4 grams (4 oz), wrapped in wax paper with tablespoon markings printed on the wrapper. One pound of butter = 4 sticks = 2 cups.

European vs American butter: American butter is 80% fat; European-style butter is 82–84% fat, which produces a richer flavour and flakier pastry. European butter is sold by weight; American butter is sold by stick count. European recipes written in grams work seamlessly with both types.

Clarified butter and ghee: produced by melting butter and removing the water (16%) and milk solids (4%), leaving pure butterfat. Ghee is clarified longer, removing all milk solids. Both have higher smoke points than regular butter and are used for high-heat cooking. Volume-for-volume, clarified butter has more fat than regular butter — recipes requiring clarified butter should not substitute regular butter by the same volume.

Tablespoon markings on butter wrapper: American butter wrappers have pre-printed tablespoon and cup markings. Cut at the ¼ cup line for ¼ cup; cut at the ½ line for ½ cup. This is why American recipes often specify butter by the tablespoon — you can measure without dirtying a measuring cup.

Gram-based precision: weighing butter on a kitchen scale (in grams) is more accurate than measuring by volume or stick, because sticks can vary slightly in length and butter packs differently in a measuring cup depending on temperature. For critical baking (laminated doughs like croissant, puff pastry, precise shortbread), weight measurement is always preferred.
