Convert Teaspoon to Tablespoon (tsp → tbsp)

Converting teaspoons to tablespoons is straightforward: multiply by the conversion factor. Follow these three steps to do it by hand or in your head.

1. 1
   Take your value in teaspoons

   Start with the number of teaspoons (tsp) you want to convert.
2. 2
   Multiply by 0.333035

   The conversion factor from tsp to tbsp is 0.333035. Multiply your value by this number.
3. 3
   Read the result in tablespoons

   The result is your value in tablespoons (tbsp).

Multiply the value in teaspoons by 0.333035. For the reverse direction, multiply by 3.002686.

• ✓1 tsp = 5 ml (practical); 4.929 ml (US legal).
• ✓3 tsp = 1 tbsp universally.
• ✓Use a proper measuring spoon — household teaspoons vary 3–8 ml.

• ✗Using a regular cutlery teaspoon for medication — can over- or under-dose by 30–60%.
• ✗Mixing tsp and tbsp — 3× difference.
• ✗Assuming "a pinch" or "a dash" is reproducible — it varies 0.1 to 0.5 ml.

What is the Teaspoon?

The teaspoon equals exactly 5 milliliters (international culinary standard) or about 4.929 mL (US strict definition based on 1/3 of a tablespoon). The teaspoon is the smallest standard cooking measure, used worldwide for spices, baking soda, vanilla extract, salt, and small ingredient quantities. A flat (level) teaspoon is the recipe convention; rounded or heaping teaspoons are inconsistent and avoided in serious cooking. The teaspoon is also a medical unit: many liquid medications are dosed in teaspoons (5 mL standard). The teaspoon relates to the tablespoon (1 tbsp = 3 tsp), the cup (48 tsp = 1 cup), the milliliter (1 tsp = 5 mL conventional), and the fluid ounce (6 tsp = 1 fl oz). Standardized 5-mL measuring spoons are available globally to avoid the variability of household teaspoons (which range from 2 to 7 mL).

What is the Tablespoon?

The tablespoon equals exactly 15 milliliters (international culinary standard) or about 14.787 mL (US strict definition based on ½ fluid ounce). The tablespoon is a near-universal cooking measure for ingredients larger than a teaspoon but smaller than a cup — typical uses include oils, sauces, and condiments. The Australian tablespoon is uniquely 20 mL (4 teaspoons rather than 3), an oddity in international recipe interpretation. Standard recipes assume 1 tbsp = 15 mL globally except in Australia and the United States (where it is sometimes 14.787 mL but commonly rounded to 15 mL). The tablespoon relates to the teaspoon (3 tsp = 1 tbsp), the cup (16 tbsp = 1 cup), the fluid ounce (2 tbsp = 1 US fl oz), and the milliliter (1 tbsp = 15 mL conventional). Measuring spoons are calibrated to the local convention.
