1 cup butter in grams
Butter cups to grams converter
One cup of butter weighs 227 grams, equivalent to 2 standard US sticks (each stick is 1/2 cup = 113 g = 4 oz). Butter is one of the few baking ingredients where the cup measurement is exact by convention — 1 cup butter equals 8 fluid ounces of volume, 8 ounces of weight, and 227 grams, the same as a cup of water. Every US butter package labels the stick as 1/2 cup = 113 g.

Convention
Two numbers? Here's why
Why two numbers? The cup-to-gram convention
Butter is exact by convention. 1 cup of butter = 8 fl oz volume = 8 oz weight = 227 g — the same as a cup of water, because solid butter's density at room temperature is very close to 1 g/mL. King Arthur Baking lists 1/2 cup = 113 g (matches), and every US butter package marks 1 stick = 1/2 cup = 113 g = 4 oz. Doves Farm's UK chart shows 240 g/cup, ~6% higher, but the 227 g convention is what US recipes and US packaging use.

How we cross-checked these numbers
Each density value is cross-referenced against at least two independent published sources. When two sources disagree by more than 5%, both conventions are shown in the "Why two numbers?" block above instead of silently picking one.

Note on accuracy
Butter is one of the rare exact-conversion baking ingredients because its density is ~1 g/mL and US recipes by convention treat 1 cup butter = 8 oz weight = 227 g (the same number a cup of water would weigh). KAF documents 1/2 cup = 113 g (i.e. 1 stick), which doubles to 226 g/cup and rounds to 227 g per the USDA/US-package convention. Doves Farm's chart lists 240 g/cup, ~6% above KAF/USDA; we follow KAF/USDA because every US butter package labels 1 stick = 113 g = 1/2 cup. g_per_tbsp = 14.2 corresponds to the standard US butter wrapper marking '1 Tbsp ≈ 14 g'.
