A standard stick of butter measures 4 ounces, which is equivalent to 1/2 cup of butter. It takes two full sticks of butter to equal 1 cup. Using tablespoons as a unit of measurement, one stick of butter is 8 tablespoons.
When measuring in pounds, an 8-tablespoon stick of butter weighs 1/4 pound. This means that two sticks weigh 1/2 pound and equal a full cup. If using the metric system, a single stick of butter equates to 113 grams by weight and 125 milliliters by volume. While butter is typically measured in sticks in the United States, other countries sell it in alternate forms. Canadians use volume while Europeans and British sell by weight.
