How Many Cups Are in a Cup of Butter?

What does 1 cup of butter mean in other units?

1 cup of butter is a standard baking measurement that equals 2 sticks of butter (in US butter packaging), 16 tablespoons, 8 ounces by weight, 1/2 pound, or 227 grams. This is one of the cleanest measurement relationships in baking because butter packaging is designed around it: each US butter stick is exactly 1/2 cup, 4 oz, 8 tablespoons, or 113 g. Two sticks make 1 cup of butter regardless of the brand. The standard 1-pound US butter package contains 4 sticks, which equals 2 cups total. For UK and European recipes, 1 cup of butter is about 227 g, which is just under a standard European butter block (typically 250 g). The 1-cup-equals-2-sticks relationship makes butter the easiest baking ingredient to measure across volume and weight systems.

How do butter sticks relate to cups?

In the US butter system, each stick is 1/2 cup, 8 tablespoons, 4 oz, or 113 g. The wrapper on each stick is marked with tablespoon lines at 1 tbsp intervals, which makes precise measurement easy without unwrapping the stick. Two sticks make 1 cup. Four sticks make 1 pound or 2 cups. For common baking recipes: 1/4 cup of butter is 1/2 stick (4 tbsp), 1/2 cup of butter is 1 stick (8 tbsp), 3/4 cup of butter is 1.5 sticks (12 tbsp), and 1 cup of butter is 2 sticks (16 tbsp).

How much does 1 cup of butter weigh?

1 cup of butter weighs exactly 8 ounces (227 grams or 1/2 pound). This is one of the cleanest weight conversions in baking because butter density is consistent (around 0.96 g per ml). Two sticks of butter (each 4 oz) make 1 cup, totaling 8 oz. A pound of butter (4 sticks) equals 2 cups. The 8 oz per cup figure is also the weight of European butter blocks, which makes converting between US and European recipes straightforward for butter specifically. For other ingredients, weight per cup varies (flour at 4.25 oz, sugar at 7 oz), but butter's 8 oz per cup is constant. This consistency makes butter the easiest baking ingredient to measure: cup, stick, tablespoon, ounce, gram, and pound measurements all line up cleanly without complicated conversions.

When does the cup-of-butter math matter most?

Baking is the main case. Cookie, cake, and pastry recipes often list butter in cup or stick amounts; converting between them through the 16 tbsp per cup, 8 tbsp per stick, and 2 sticks per cup relationships handles most situations. Recipe scaling benefits from the clean math: halving a 1-cup butter amount gives 1/2 cup (1 stick); quartering gives 1/4 cup (4 tbsp). International recipe conversion requires the gram equivalent (1 cup equals 227 g), since European recipes list butter by weight. Substituting butter for oil or shortening uses the cup-to-cup ratio with adjustments (typically use 3/4 cup oil for 1 cup butter due to no water content in oil). For everyday baking, knowing 1 cup butter equals 2 sticks is the foundational fact that handles most situations.
