Butter (unsalted): Grams to Cups
1 cup of butter (unsalted) = 227 grams
One US cup of butter (unsalted) weighs 227 grams. One 250 ml metric cup — the one used in the UK, Australia, New Zealand and Canada — holds 240 grams. To convert any weight, divide the grams by the figure for your cup.
A cup of butter weighs 227 g (USDA FoodData Central) — two US sticks of 113 g, or 16 tablespoons at about 14.2 g each. It is one of the few ingredients where the wrapper does the measuring for you.
Sticks, blocks and tablespoons
US butter is sold in 4 oz (113 g) sticks marked in 8 tablespoons, so ½ cup is one stick and 1 cup is two. European and Australian butter usually comes in 250 g blocks, which is 1.1 cups — just over two US sticks. UK recipes often give butter in grams directly.
West-coast US sticks are shorter and fatter than east-coast ones but weigh the same 113 g, so the tablespoon markings still apply.
Melted, softened or cold — the weight does not change
Melting changes the volume very slightly but not the weight. If a recipe says "½ cup butter, melted", measure 113 g of solid butter and then melt it; do not melt butter and then fill a half-cup. For softened butter pressed into a measuring cup, air pockets make it easy to under-fill — the stick markings or a scale are far more accurate.
Salted or unsalted
Salted and unsalted butter weigh the same per cup (USDA lists 227 g for both). Salted butter carries roughly ¼ teaspoon of salt per stick, so if you swap it in, cut the recipe's salt by about that much per 113 g.

How to measure butter (unsalted) accurately
The 227 g figure assumes the spooned-and-levelled method: spoon the butter (unsalted) into a dry measuring cup and sweep the top flat with a straight edge. Scooping the cup through the bag compacts it and gives a heavier cup.
