Teaspoons in Cooking vs Medicine
Teaspoons are used in two very different contexts and it’s important to know the difference:
Cooking teaspoons — a standard US/UK cooking teaspoon is 4.929ml. This is what recipes mean when they say “1 tsp” of vanilla extract, baking powder or salt.
Medicine teaspoons — in medical contexts, 1 teaspoon is standardised at exactly 5ml. Most liquid medicines use this measurement. If in doubt, always use a proper medicine measuring spoon or syringe rather than a kitchen teaspoon, as kitchen spoons can vary in size.
Common Recipe Teaspoon Measurements
Here are the most frequently used teaspoon measurements in cooking and baking:
- ¼ tsp salt = 1.23ml — standard pinch for most recipes
- ½ tsp baking powder = 2.46ml — common in cake recipes
- 1 tsp vanilla extract = 4.93ml — standard for most baking
- 1 tsp olive oil = 4.93ml — common in salad dressings
- 2 tsp yeast = 9.86ml — typical for bread recipes
- 1 tbsp (3 tsp) = 14.79ml — the next measurement up from a teaspoon
