How many ml in a teaspoon? Here are the teaspoon to ml, and ml to teaspoon conversions you need for easy cooking and baking in the kitchen, plus a handy online and printable conversion chart for quick reference.
Use this online kitchen cheat sheet and printable conversion chart to find how many milliliters are in a teaspoon, check other common kitchen amounts, and quickly convert ml to teaspoons and teaspoons to ml.
Between a treasured mix of family recipes from both the US and Italy, and a love for dishes from across the Mediterranean and around the world, we’ve spent a lot of time converting between US and metric units. After all these years, you’d think we’d have all the most common kitchen conversions memorized! But the truth is, we still find ourselves searching for the exact same equivalents again and again.
So, I’ve created quick-reference guides for the most pressing kitchen conversion needs, including how many ml in a teaspoon (and how many ml in a tablespoon). No matter what side of the pond your recipe comes from, you’ll easily find the measurements you need.
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.)

Common ml to tsp conversions
- 1 ml equals how many teaspoons? (1 ml to tsp)
1 milliliter is equivalent to 1/5th of a teaspoon (.2 tsp),
a bit of a challenge to measure.
Since that size measuring spoon is rare in the kitchen, a 1/4 tsp (.25 tsp/1.25ml) measuring spoon would be the closest kitchen substitute (and a scant 1/4 tsp may be even closer). Other ideas are to use an eyedropper or pipette. (Or with water, you could use a digital kitchen scale using the gram (g) unit, since 1 mL of water equals 1 g.) - 5 ml equals how many teaspoons?
