Teaspoons to Milliliters Converter

The teaspoon here is the US teaspoon, exactly 4.92892159375 ml, which the result box shows as 4.9289 ml. Measuring-spoon sets come in fractions, so these are the figures you will use most:

You can type the fraction exactly as it is printed on the spoon, such as 1/8 or 3/4, or a mixed amount like 1 1/2 with a space in the middle.

Recipes sometimes ask for a pinch or a dash. Those have no fixed volume and aren't in the converter's unit list, so there is nothing to convert. Use the smallest spoon in your set, or less, and adjust to taste.

Many measuring spoons are marked 5 ml, and recipes written in milliliters often assume one. That spoon is 1.44% larger than the US teaspoon in this tool. Press the swap button, type 5, and the tool shows 1.0144 teaspoons.

In a recipe, that gap is far smaller than the difference between a level and a heaped spoon, so either spoon works. What matters more is levelling. Scrape the top flat with a knife for baking soda, baking powder and salt, where a heaped spoon throws the balance off far more than the choice of spoon.

Teaspoon amounts become awkward when you multiply a recipe. Half a teaspoon of vanilla in each of 8 batches is 4 teaspoons, or 19.7157 ml. Rather than counting out eight half-spoons, measure 1 tablespoon plus 1 teaspoon. Three teaspoons show as exactly 1 tablespoon in this tool.

Once you pass about 3 tablespoons, a jug or a cup measure becomes easier than spoons. The converter's cup is the US cup, exactly 48 teaspoons, so you can switch the To menu to cups and read the amount straight off: 48 teaspoons show as 1 cup.

A dose written as "5 ml" or "1 teaspoon" on a medicine label is best measured with the syringe, cup or spoon supplied with it, when there is one. Spoons from a cutlery drawer are not made to any standard volume, and they can be well off a measured teaspoon. Use this converter to understand a label written in one unit when your measuring device is marked in the other, not to replace the device.
