What You'll Learn
There are 5ml in a teaspoon
The teaspoon was originally used as a unit of Apothecaries' measure and was equal to 1 fluid dram, ¼ of a tablespoon, or 1/8 of a fluid ounce. This definition of the teaspoon is smaller than the definitions of the teaspoon used today. This is partially due to tea being expensive in 1660s England, resulting in smaller teacups and teaspoons. Once England began importing tea from China in 1710, reducing the cost of tea, the size of teacups and teaspoons increased, and by the 1730s, became 1/3, rather than 1/4 the size of a tablespoon.
For more accuracy, a standardised teaspoon made of a stable material like stainless steel is recommended. The National Institute of Standards and Technology (NIST) gives the figure of 4.93ml per US teaspoon, which is then rounded to 5ml.

It's worth noting that 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 standardised teaspoon made of a stable material like stainless steel is recommended.

The shape of the teaspoon affects the volume
The volume of a teaspoon can be affected by its shape, size and accuracy. A standard teaspoon is a unit of volume commonly used for measuring small amounts in cooking. There are 5 ml in a teaspoon, but this can vary depending on the country. The US teaspoon, for example, measures 4.92892 mL, while the metric teaspoon is 5 mL. The shape of the teaspoon can also affect the volume, as the size and accuracy of a plastic teaspoon can be affected by heat, time and use. For instance, a teaspoon with a deeper bowl will hold more liquid than one with a shallower bowl, even if the diameter of the bowl is the same. Therefore, it is recommended to use a standardised teaspoon made of a stable material like stainless steel for more accuracy.

The material of the teaspoon affects the volume
The material of the teaspoon does affect the volume. For example, the US teaspoon is made of stainless steel and holds 4.93 ml, which is then rounded to 5 ml. The metric teaspoon is also 5 ml. However, the exact volume in a teaspoon also depends on how you pour it, the shape of the teaspoon, and the material.
