There are exactly 4.93 ml in a US measuring teaspoon which is often approximated to 5ml hence, it is reported as 5ml in a teaspoon.
For metric measurements (used in the UK, Australia, etc.), there are exactly 5 ml in a metric measuring teaspoon.
There is a difference between a measuring teaspoon and a teaspoon for eating of a cutlery set. A normal cutlery teaspoon that we use for food is about 2.5 ml on average and differs depending on its size.
This is because cutleries do not have a standard size that companies abide by when producing them considering they are made just for eating and other domestic uses.
Below is a table that converts teaspoons to ml and vice versa;
| US Teaspoons (tsp) | Milliliters (ml) |
| 1 teaspoon | 4.93 ml |
| 2 teaspoons | 9.86 ml |
| 3 teaspoons | 14.79 ml |
| 4 teaspoons | 19.72 ml |
| 5 teaspoons | 24.64 ml |
| 6 teaspoons | 29.58 ml |
| 7 teaspoons | 34.5 ml |
| 8 teaspoons | 39.43 ml |
| 9 teaspoons | 44.36 ml |
| 10 teaspoons | 49.29 ml |

What is a mililiter (ml)?
A milliliter is a volume measurement with the symbol of (ml) meaning, it is not measured by a weight scale but rather, by the size of the container it occupies.
The milliliter is the smaller unit of the bigger standard liquid measurement of liters (or litres) where 1 liter = 1000ml.
This smaller unit is used to measure smaller everyday containers or quantities for ease such as liquid medicines, soda cans, oils, perfumes, toothpaste, etc.
what is a measuring teaspoon?
For most people, a teaspoon (with the symbol tsp)is a small spoon found in a cutlery set that is used to eat with.
However, a measuring teaspoon is used in cooking and baking recipes. It measures the volume of both liquid and dry ingredients but not their weight.
Teaspoons are commonly used for measuring liquid drug prescriptions and recipes to measure small quantities of ingredients but not much beyond that.
types of teaspoons?
All teaspoons are not made equal even if they are measuring teaspoons and not cutlery. There are about 5 types of measuring teaspoons in the world but the most common ones that 90% of the human population use are the Us teaspoon and the metric teaspoon.
US teaspoon
The Us teaspoon was adopted in the Us and contains 4.93 ml approximately 5 ml of liquid. Industries and food companies use the standard 5 ml for one teaspoon.
Metric teaspoon
The metric teaspoon has a measurement of exactly 5 ml and is adopted in the UK, Australia, Canada and other commonwealth countries
Though New Zealand doesn’t use the metric teaspoon for its measurements, its teaspoon also exactly measures 5ml
How to convert teaspoons to milliliters
Many recipes need us to do some conversion before mearing our ingredients and it is especially important that we get the measurements right when we are baking because baking is a lot more sensitive than cooking.
It is quite simple to convert teaspoons to milliliters. For example, if you want to know how many milliliters in 1.5 teaspoons, simply multiply the number of teaspoons by the volume of the type of teaspoon used.
i.e. 1.5 teaspoons x 4.93 ml (a US teaspoon)
= 7.395 ml.
or 1.5 teaspoons x 5 ml (a metric teaspoon)
= 7.5 ml.
DRY Measurement terminologies
It is common for recipes to specify how to measure ingredients. Below are the three most common terms:
- Leveled – A leveled spoon or cup means using another spoon to scoop the ingredient into the measuring container to a heap then use the blunt flat edge of a knife or a spoon to level it by passing it over the edge of the spoon or cup
- Heaped – This means piling as much of the ingredient on the spoon or cup without it falling off
- Rounded – A rounded spoon means a slightly heaped spoon where the ingredients rise slightly above the edge of the spoon in a rounded shape.
