The Golden Tablespoon to Cup Formula
Converting tablespoons to cups is straightforward because both units measure volume. Unlike grams-to-cups conversions that depend on ingredient density, the ratio of tablespoons to cups is constant: exactly 16 tablespoons per US cup.
Use the formula: cups = tablespoons ÷ 16. For example, 12 tablespoons divided by 16 equals 0.75 or 3/4 cup. 4 tablespoons divided by 16 equals 0.25 or 1/4 cup.

Measuring Butter: Sticks, Tablespoons, and Cups
In American baking, butter is commonly sold in 4-ounce sticks with tablespoon markers. One full stick of butter equals 8 tablespoons (1/2 cup), and two sticks equal 16 tablespoons (1 full cup).
If a recipe calls for 6 tablespoons of butter, slice along the wrapper marks, which equals 3/8 of a cup (85 grams).
