About converting teaspoons to milliliters
Small measurements can still matter a lot
Teaspoons show up in recipes whenever a small amount can have a big effect: vanilla extract, baking powder, lemon juice, syrups, spice blends, and flavor concentrates. Because many kitchen tools outside the US use milliliters instead of teaspoons, tsp to ml is a practical conversion for everyday cooking and baking rather than a niche one.
Kitchen formula
A US teaspoon is about 4.92892 milliliters, which most cooks round to 5 ml. That rounded value is useful for mental estimates, but the exact figure helps when you are scaling several small spoon measurements together or converting a recipe for more precise prep.

This converter is useful for baking ingredients, extracts, syrups, sauces, and drink recipes where small liquid amounts matter. If a recipe calls for 3 teaspoons of vanilla or lemon juice and your measuring tools are marked only in milliliters, this page gives you a quick kitchen-ready answer.

About this converter
tool notesVolume conversions are most useful when liquids, recipes, and packaging labels refuse to stick to one unit system. A recipe might use cups, a bottle may show fluid ounces, and product packaging often switches to milliliters or liters. This hub brings those everyday conversions together so you can move quickly from a kitchen measurement to a packaging check or a beverage portion comparison. The goal is not just to provide a calculator, but to make common liquid-size conversions easier to scan, understand, and reuse across cooking, shopping, and product research.
