In the United States, one stick of butter equals 8 U.S. tablespoons. If you are using the British Imperial measurement system, one stick of butter equals 6.66 U.S. tablespoons. In the metric system, this is equivalent to 118.29 milliliters.
Many people outside the U.S. who attempt to convert quantities in recipes find the "stick of butter" measurement to be confusing, as their countries do not necessarily use the same measurements for packaging butter. If you are used to measuring butter on a scale before adding it to your other ingredients, a stick of butter in the U.S. weighs 0.25 pound, or 113.4 grams.
