Tips & best practices

  • Remember the core fact: 1 tablespoon equals 3 teaspoons. Almost every other conversion follows from it.
  • For 1/3 cup, measure 5 tablespoons plus 1 teaspoon — it is the only awkward fraction in the US system.
  • Level off dry ingredients in the spoon with a straight edge so each measure is consistent.
  • Keep a set of measuring spoons that includes a 1/2 tablespoon to avoid awkward teaspoon math.
  • When halving a recipe, convert tablespoons to teaspoons first — it makes the smaller amounts easier to split.

Frequently asked questions

How many teaspoons are in a tablespoon?
There are exactly 3 teaspoons in 1 tablespoon. This holds for the standard US measuring spoons used in most recipes.
How many tablespoons are in a cup?
There are 16 tablespoons in 1 US cup, which is the same as 48 teaspoons or 8 fluid ounces.
How many teaspoons are in a cup?
There are 48 teaspoons in 1 US cup. That follows from 16 tablespoons per cup and 3 teaspoons per tablespoon.
What is 1/3 cup in tablespoons?
One-third of a cup is 5 tablespoons plus 1 teaspoon, which equals 16 teaspoons total. It is the one common fraction that does not divide into whole tablespoons.
How many tablespoons are in a fluid ounce?
There are 2 tablespoons in 1 fluid ounce, which is the same as 6 teaspoons.
Why would I need to convert tablespoons to teaspoons?
It is handy when you have lost a measuring spoon, when you are scaling a recipe up or down, or when a recipe lists an unusual amount and you only have certain spoons clean.
Are US and metric tablespoons the same size?
Not quite. A US tablespoon is about 14.8 millilitres, while an Australian tablespoon is 20 millilitres. This converter uses US measuring spoons, where 1 tablespoon is 3 teaspoons.
Can I measure dry and wet ingredients with the same spoons?
Yes. Measuring spoons work for both dry and liquid ingredients. The volume of a tablespoon or teaspoon is the same whether you are scooping salt or vanilla extract.
