Here you’ll find an online cheatsheet, plus a conversion chart (with printable version) with how many milliliters in a teaspoon, and other common amounts, so you can quickly get ml to teaspoons, and teaspoons to ml, conversions.
We’ve always done a lot of converting back and forth between US and metric measuring units, with family recipes and cookbooks from both the US and Italy, supplemented with other region’s, and now today’s online recipes from around the world. After years, you’d think I’d remember more kitchen conversions! But I still search out the same measurement equivalents again and again.
Hence, I’ve created quick references to the most pressing kitchen conversion needs, including how many ml in a teaspoon (and how many ml in a tablespoon). So no matter what side of the pond your recipe is on, you’ll be able to quickly get the right measurements.
The Basics
- What is a ml? A ml, also written as mL, is the abbreviation for milliliter or millilitre, a unit of volume, or capacity of the metric system. A milliliter equals 1/1000 of a liter, the basic metric unit of volume.
- What is a teaspoon? A standard teaspoon is a unit of volume commonly used for measuring small amounts in cooking.
How many ml in a teaspoon?
There are 5 ml in a teaspoon.
Note, Although a standard measuring teaspoon generally falls around 5 milliliters, there can be differences between teaspoons in different countries.
The exact volume in a teaspoon also depends on how you pour it, the shape of the teaspoon, and the material (the shape, size and accuracy of a plastic teaspoon can be affected by heat, time, and use).
For more accuracy, a standardized teaspoon made of a stable material like stainless steel is recommended.
(Need the exact figure? 4.93 ml per US teaspoon is the figure given by the NIST (National Institute of Standards and Technology – Weights & Measures), which is then rounded to 5 ml for cooking purposes.
