Are you tired of constantly Googling the conversion rate for teaspoons to milliliters? Bookmark our teaspoon-to-ml converter!

But first, let's clear up the confusion between the two main measuring systems. The Imperial system, also known as the British system, is commonly used in the United Kingdom and other Commonwealth countries, while the metric system is used in most other parts of the world. One of the main differences between the two systems is the unit of measurement used for volume. In the Imperial system, volume is measured in fluid ounces, while in the metric system, volume is measured in milliliters.

Teaspoons in each system:

In the Imperial system, a teaspoon is equivalent to 4.93 milliliters or 0.17 fluid ounces. In the metric system, a teaspoon is equivalent to 5 milliliters.

Formula for Converting Teaspoons to Milliliters

The formula for converting teaspoons to milliliters depends on the type of teaspoon being used. There are two main types of teaspoons: the metric teaspoon and the Imperial teaspoon.

Metric Teaspoon Formula: 1 tsp = 5 ml

Imperial Teaspoon Formula: 1 tsp = 4.93 ml

Here's an example to help illustrate how the formula works:

Let's say you have a recipe that calls for 2 teaspoons of vanilla extract, but you need to convert that measurement to milliliters because your measuring cups and spoons are in the metric system. Using the formula for the metric teaspoon, you would simply multiply 2 by 5 to get:

2 tsp x 5 ml/tsp = 10 ml

So, you would need 10 milliliters of vanilla extract for your recipe.

Types of Teaspoons in Metric & Imperial Systems

As mentioned earlier, there are different types of teaspoons in the metric and Imperial systems.

Here's a useful table that compares the two types:

Metric Teaspoon Imperial Teaspoon
Volume 5 ml 4.93 ml
Usage Metric System Imperial System
Countries Most countries UK, Canada, etc.
Small spoon N/A 1/2 Imperial tsp
Abbreviation tsp tsp or t

As you can see, the main difference between the two types of teaspoons is the volume measurement, but there are also differences in usage and which countries primarily use each system. Additionally, the Imperial system has a smaller teaspoon, also known as a coffee spoon or demi-tasse spoon, which is equivalent to 2.46 milliliters or 1/2 of an Imperial teaspoon. It's important to keep these differences in mind when converting between teaspoons and milliliters.
