How it works
Butter is one of the most unit-confusing ingredients in the kitchen, and this butter converter calculator settles the confusion by translating any amount between US sticks, cups, tablespoons, teaspoons, ounces and grams. American recipes wrap butter in sticks, British and European recipes weigh it in grams, and older recipes scatter tablespoons and cups throughout, so cooks constantly need to move between them. Getting the conversion right matters because butter carries structure, moisture and richness in a recipe, and being off by half a stick can leave a cookie flat or a sauce split. A butter converter calculator removes the mental arithmetic and the risk of misremembering that a stick is not quite a quarter cup by volume but is a clean 113 grams by weight, which is the figure most professional bakers actually work from. The conversion works because each unit corresponds to a fixed weight of butter: a US stick is 113 grams, a cup is 227 grams, a tablespoon is 14.2 grams, a teaspoon is 4.73 grams and an ounce is 28.35 grams. The tool reduces whatever you enter to grams and then scales out to the unit you want, so the answer stays exact in either direction. Home bakers following recipes from different countries, anyone weighing on a kitchen scale, and cooks halving or doubling a batch all rely on a butter converter calculator to keep quantities honest.
grams = amount × grams-per-unit; target = grams ÷ grams-per-target-unit
Butter is sold and measured in a tangle of units — sticks, cups, tablespoons, ounces and grams — that all describe the same physical block. Each unit maps to a fixed weight: a US stick is 113 grams, a cup 227, a tablespoon 14.2, a teaspoon 4.73 and an ounce 28.35. The converter reduces your amount to grams by multiplying by its unit's weight, then divides by the target unit's weight. Pivoting through grams as the common base keeps every pairing exact and means only one factor per unit is needed rather than a rule for each combination.

Frequently asked questions
How many grams are in a stick of butter?
A standard US stick of butter weighs 113 grams, equal to a quarter pound or four ounces. It also equals half a cup or eight tablespoons. Most American recipes assume this size, so when a recipe calls for one stick you can weigh out 113 grams on a scale instead. Using the gram figure is the most reliable way to follow a US recipe with metric measuring tools.
How much is a cup of butter?
One cup of butter weighs about 227 grams, which is two US sticks, half a pound, or sixteen tablespoons. Because butter is a solid packed into a volume measure, weighing it is far more accurate than pressing it into a measuring cup, where air gaps and soft spots skew the amount. Set the from-unit to cups and the to-unit to grams to get the exact weight for your recipe.
Why convert butter by weight instead of volume?
Butter is a solid, so measuring it by volume in cups or tablespoons is imprecise — how firmly you pack it changes the amount, and softened butter measures differently from cold. Weighing in grams removes that variability entirely, which is why bakeries and precise recipes specify grams. This converter lets you turn any volume measure into grams so you can weigh the exact amount your recipe intends every time.
Are US and European butter sticks the same?
Not always. The US stick is 113 grams and is long and thin, while butter in many European countries is sold in 250-gram blocks with no stick markings at all. Some regions also use shorter, fatter sticks. Because of this variation, converting by weight in grams is the safest approach — a gram is a gram everywhere, so weighing sidesteps any difference in how sticks are shaped or portioned.
How many tablespoons are in a stick of butter?
A US stick holds eight tablespoons, and each tablespoon of butter weighs about 14.2 grams. Many stick wrappers are printed with tablespoon markings so you can slice off what you need. If your butter has no markings, weigh 14.2 grams per tablespoon instead, or use this converter to translate the tablespoons a recipe asks for into grams or into a fraction of a stick or cup.
