Cups to Tablespoons Converter
Cups-to-tablespoons is what you reach for when scaling a recipe down — turning a one-cup quantity from a family-of-four recipe into the 4 tablespoons that feed one person, or scaling a half-cup of olive oil into the 8 tablespoons your individual portion requires. The math is exact: there are 16 tablespoons in one US cup, so multiplying cups by 16 gives the answer with no rounding required at any scale.

1 × 16 = 16.0000
Formula
Multiply cups by 16 to get tablespoons. 1 cup = 16 tbsp; 0.5 cup = 8 tbsp; 0.25 cup = 4 tbsp; 0.125 cup = 2 tbsp. Every fractional cup measure on a standard American set converts to a clean tablespoon count: 1/3 cup = 5 tbsp + 1 tsp; 2/3 cup = 10 tbsp + 2 tsp.
Where You'll Use This
Scaling a recipe down to single-serving size often pushes cup quantities into tablespoon territory. Salad dressings — a recipe that calls for 1/4 cup of vinegar may need to be cut to 4 tablespoons for a smaller bowl. Spice rubs scaling from a full batch (1 cup of mixed spices) down to single use (a few tablespoons applied to one steak) require this conversion. Coffee brewing where a recipe calls for 1/2 cup of ground coffee per pot may need to be cut to 8 tablespoons for a half-pot.

A Bit of History
Fannie Farmer's 1896 Boston Cooking-School Cook Book pinned the American tablespoon at 1/2 fluid ounce and the cup at 8 fluid ounces, giving the world the clean 16-tablespoons-per-cup ratio that has held ever since. Before Farmer standardized measurements, American recipes used phrases like 'a wine-glassful' or 'a teacupful' with no fixed meaning, and home cooks were expected to know what each phrase meant by feel. The post-Farmer measuring-cup-and-spoon set is one of the most enduring artifacts of the American Progressive-era domestic-science movement.
FAQ
How many tablespoons is 1/4 cup?
4 tablespoons. The quarter-cup measure on every American measuring set equals exactly 4 tbsp.
How many tablespoons is 1/2 cup?
8 tablespoons. The half-cup measure equals exactly 8 tbsp — useful when scaling recipes down or measuring butter that comes in tablespoon-marked sticks.
How many tablespoons is 1/3 cup?
5 tablespoons plus 1 teaspoon (5 tbsp + 1 tsp = 16 tsp = 1/3 of 48 tsp = 16/48). The 1/3 cup is the only fractional cup measure that doesn't divide evenly into tablespoons, which is why most precision recipes specify either tablespoons or grams instead.
