Plastic spoons are used for a variety of purposes, from eating to measuring. While there is no standard size for household spoons, a typical teaspoon is generally accepted to hold 5 milliliters (mL), with a smaller 2.5 mL often used for measuring. The volume of a household spoon can vary, with some teaspoons holding as little as 3 mL and as much as 7 mL. In the medical field, the use of household spoons to administer liquid medication is discouraged due to the risk of overdosing or underdosing, with studies showing that individuals often struggle to accurately measure 5 mL of liquid medicine into spoons of various sizes.

What You'll Learn
A teaspoon is 5ml
Using a household spoon to measure medication can be dangerous and lead to an overdose or underdose. For example, a child who is supposed to take a 1/4 teaspoon dose of a critical liquid medication could receive a 20% underdose if the teaspoon holds 5ml, or a 25% overdose if the 1/4 teaspoon is equal to 1ml. This is why liquid medications come with their own measuring devices, such as a dosing syringe, spoon or cup.
It is also important to note that 5ml of liquid in a teaspoon will look like a lot, whereas the same amount in a larger spoon will appear to be less, which can result in people adding more liquid. This is why standardised measuring spoons are important.
A teaspoon can be abbreviated as 't' or 'tsp' and a tablespoon as 'Tbsp'.

A tablespoon is 15ml
A tablespoon is equal to three teaspoons, which hold 5ml each. So, if you have a set of measuring spoons, you can use these to measure out 15ml. If you don't have a set of measuring spoons, you can use a measuring jug or a medicine cap to measure out 15ml.
It's also possible to estimate 15ml using your finger. A teaspoon is roughly equal to the first knuckle of your index finger. So, a tablespoon, or three teaspoons, would be roughly equal to three knuckles on your index finger.
It's worth noting that, when it comes to medication, it's always best to use a proper measuring device, like a syringe or a dosing cup, rather than a spoon. This is because the dose of medication is often very precise, and even a small overdose or underdose can be dangerous, especially for children.

Household spoons are not standardised
A typical household teaspoon can hold between 3 and 7 milliliters (mL), and a tablespoon can hold 15 mL. However, these measurements are not exact, and the size and shape of spoons can vary significantly. When it comes to medication, even a small overdose or underdose can have serious consequences. For example, acetaminophen, an ingredient in popular medications like Tylenol and NyQuil, can cause liver stress and has been linked to emergency room visits, hospitalizations, and even deaths in cases of overdose.
In a study conducted by Cornell University, participants were asked to pour out 1 teaspoon (5 mL) of cold medicine into kitchen spoons of different sizes. They consistently made errors, pouring out too little or too much, depending on the spoon size. This demonstrates the lack of standardisation in household spoons and the potential risks associated with using them for medication.
To ensure accurate dosing, it is recommended to use measuring devices specifically designed for medication administration, such as dosing syringes, cups, or droppers. These devices provide clear millilitre (mL) markings, allowing for precise measurement. By prescribing medication in millilitres and providing appropriate measuring tools, doctors can help patients avoid the dangers of inaccurate dosing.

Metric measuring spoons are available in sets
A teaspoon is 5ml, and a tablespoon is 15ml. Regular spoons, however, are not reliable for measurements. Cutlery spoons are not made to standard sizes and may hold 2.5ml-7.3ml for teaspoons and 7ml-20ml for tablespoons.
When choosing a set of measuring spoons, it is important to consider accuracy and usability. Some sets may be clumsy to hold or difficult to clean due to their design. It is also worth noting that the labels denoting standard and metric values can sometimes be challenging to read. Additionally, features like an easily removable ring or a magnet embedded in the handle can enhance the user experience.
Several sources recommend the Sur La Table Spice Measuring Spoons for their accuracy, durability, and ability to fit into narrow spice jars. The Prepworks by Progressive Magnetic Measuring Spoons are another good option, offering the convenience of double-ended spoons and easy separation due to the magnets in the handles.

Small spoons are around 1 teaspoon in size
A teaspoon is a unit of volume measure equal to around 5ml. A small spoon, such as one used for stirring coffee or adding sugar to tea, is about one teaspoon in size. This means a small plastic spoon holds around 5ml.
It's important to note that household spoons are not standardised and deliver only an approximate dose. A typical household teaspoon can hold between 3 and 7ml.
While a teaspoon is a convenient unit of measurement, it is not always precise. For example, when measuring oral liquid medication, using a household spoon can result in an overdose or underdose. This is because the amount of liquid in a teaspoon can vary depending on the size and shape of the spoon. In addition, the same volume of liquid can look like a lot on a small spoon, but too little on a larger spoon, influencing the amount poured. For this reason, it is recommended that oral liquid medications are measured in millilitres, using a device such as a dosing syringe, cup, or calibrated dropper.
When measuring ingredients for baking, a small plastic spoon of around 5ml can be used in a pinch if no measuring spoon is available. However, it is important to note that these spoons are not always accurate and can result in an incorrect measurement. It is always best to use a standardised measuring spoon, which will be more precise.

Frequently asked questions
A teaspoon is a unit of volume measure equal to 1/3 tablespoon. It is exactly equal to 5 ml. A tablespoon is equal to 15 ml.
In 1975, the American Academy of Pediatrics pointed out that using a household spoon to give liquid medication is inaccurate. Using a medium-size tablespoon may lead to an underdose, while a large tablespoon may lead to an overdose.
Most liquid medications come with their own measuring devices, like a dosing syringe, spoon or cup. The strength of oral liquid medications is usually labelled in terms of how much active drug is in 1 ml or 5 ml.
Unlike doses for adults, those for children tend to be very precise, so even a small overdose is something to be avoided. Doctors could prescribe in milliliters so that oral syringes can be used as measuring devices, allowing for more accurate measurement.
