how big is a teaspoon
A standard kitchen teaspoon is about 5 milliliters (mL) of liquid, though the exact size can vary slightly by country.
Quick Scoop: Exact Size
- In the US, a “teaspoon” for recipes is defined as about 4.93 mL.
- In most metric countries (UK, Australia, much of Europe), a teaspoon is rounded to exactly 5 mL.
- Nutrition labels and most modern cookbooks also treat 1 teaspoon as 5 mL for simplicity.
Teaspoon vs Other Spoons
- 1 tablespoon is 3 teaspoons , so roughly 15 mL.
- A fluid ounce is about 6 teaspoons in US measures.
- These relationships are why many measuring spoon sets come in ¼, ½, 1 teaspoon and 1 tablespoon sizes.
Real-World Feel
A level measuring teaspoon is a small volume:
- Roughly the amount of liquid that just covers the bottom of a standard soup spoon.
- A typical sip of water from a glass is several teaspoons at once, which is why a teaspoon of something feels so small.
When Precision Matters
- For cooking and baking, use a proper measuring teaspoon, not a random tea or coffee spoon from a cutlery drawer, as their volumes vary a lot.
- For medicine (like cough syrup), follow the marked 5 mL line on the dosing cup or syringe instead of eyeballing a household spoon.
