Converting us cup to tablespoon comes up frequently in cooking, chemistry, medicine, and engineering. A recipe written in metric units may need to be adapted for a kitchen using tablespoon, or a laboratory protocol may specify volumes in us cup that need to be measured with equipment calibrated in tablespoon.
In everyday use, knowing that 5 cup = 80 tbsp and 10 cup = 160 tbsp covers most common situations. For bulk calculations, 100 cup = 1600 tbsp is a useful anchor. The reverse conversion — tablespoon back to us cup — uses the factor 0.0625, so 1 tbsp = 0.0625 cup.
All conversions use the internationally recognized factor of exactly 1 cup = 16 tbsp. Calculations are performed in IEEE 754 double-precision floating point, giving accuracy to at least 8 significant figures — more than sufficient for any practical application.
Formula: Tablespoon = US Cup × 15.999946
Multiply any us cup value by 15.999946 to get tablespoon. One us cup equals 15.999946 tbsp.
Reverse: US Cup = Tablespoon × 0.062500211
Cups × 16 = tablespoons. One cup = exactly 16 tablespoons.
½ cup = 8 tbsp, ¼ cup = 4 tbsp.
Tablespoons ÷ 16 = cups.
Follows American recipes using cups for flour, sugar, milk, and butter.
Tests and standardizes recipes in cup measurements before international publication.
Uses cup portions as standardized serving-size references for dietary counseling.
Teaches beginner cooks using cups as intuitive, equipment-free measuring tools.
Converts cup-based recipes to liter or kilogram quantities for industrial production.
Converts US cup measurements to metric mL when cooking American recipes abroad.
The US customary cup is defined as exactly 8 US fluid ounces, or 236.588 mL. It was standardized by Fannie Farmer in her 1896 cookbook The Boston Cooking-School Cook Book.
The cup is the backbone of US baking: nearly every American recipe uses cup measurements for flour, sugar, butter, and liquids. Standard sets include 1 cup, ½ cup, ⅓ cup, and ¼ cup.
Interesting fact: Australia uses a metric cup of 250 mL, slightly larger than the US cup, which can cause recipe confusion in international cooking.
The US tablespoon is defined as exactly 3 teaspoons or ½ fluid ounce, approximately 14.787 mL. Standardization arrived in the late 19th century alongside modern recipe writing.
Tablespoons are fundamental to cooking and medicine. The Australian tablespoon is 20 mL, the UK tablespoon is 17.76 mL, and the US tablespoon is 14.79 mL.
Interesting fact: Capital T for tablespoon versus lowercase tsp for teaspoon is a convention designed to prevent dangerous dosing errors in medical and culinary contexts.
