Cups to Tablespoons

Cups and tablespoons both measure volume — they are just two rungs on the same US customary ladder. A cup is the larger unit, so any amount expressed in cups becomes a bigger number in tablespoons. The conversion is a single multiplication; the only thing to memorize is that there are exactly sixteen tablespoons in every cup.

Two real steps. The arithmetic is a simple multiplication — no rounding required for whole and half cups.

1. 1

   Know the factor

   One US cup equals exactly 16 US tablespoons. Write it down or commit it to memory — it is the only number you need.

   1 cup = 16 tbsp
2. 2

   Multiply the cups

   Multiply your cup measurement by 16. The product is the same volume in tablespoons. For a fraction of a cup, the decimal multiplied by 16 gives the exact tablespoon count.

   0.75 × 16 = 12 tbsp
3. 3

   Check the direction

   The tablespoon figure should be larger — sixteen times larger for a full cup. If your answer came out smaller, you divided when you should have multiplied.
