Common mistakes

  • Mixing up unit definitions — US tablespoon = 14.79 mL; a UK/metric tablespoon is 15 mL.
  • Rounding too early. Multiply by the full factor (14.78676478) first, then round only the final milliliters value.
  • Converting the wrong way. This page goes Tablespoons (US) → Milliliters; to go back, divide by 14.78676478.

Frequently asked questions

How is a US tablespoon different from a metric tablespoon?

A US tablespoon is 14.79 mL, while a metric (or UK) tablespoon is exactly 15 mL. The difference is tiny (about 0.5 mL), but it matters in oil-heavy dressings and delicate sauces.

Why are tablespoon measurements so common in recipes?

Tablespoons are convenient for small to medium quantities (oils, spices, condiments, extracts). They sit between teaspoons and cups and are easy to measure with standard flatware-style spoons.

Can I use a regular flatware tablespoon from my drawer?

No. Regular eating spoons vary wildly in size (10–20 mL). Always use a standard measuring spoon (usually marked 'tbsp') or convert to mL and use a scale or syringe for accuracy.

What's the best way to measure sticky ingredients like honey or nut butter?

For sticky items, spray your measuring spoon lightly with cooking spray first, or measure in grams with a scale. If you must use mL, level the tablespoon and assume about 14.8 mL per heaping spoonful.

Is there a difference between a 'heaping' and a 'level' tablespoon?

Yes—a heaping tablespoon can be 18–20 mL, while a level one is 14.79 mL. Recipes that call for 'heaping' tablespoons are less precise; always level unless the recipe explicitly says 'heaping.'

How many tablespoons are in a cup?

16 US tablespoons equal 1 US cup (236.6 mL). So 1 tbsp = 236.6 ÷ 16 = 14.79 mL.
