The world of cooking and baking is a fascinating blend of science and art. Precision is often key, especially when following recipes where ingredient ratios can significantly impact the final outcome. Among the most commonly used measurements are tablespoons and milliliters (ml). But the simple question of whether a tablespoon equals 20ml isn’t as straightforward as it seems.
Delving into the Nuances of Tablespoon Measurements
The relationship between tablespoons and milliliters isn’t a fixed, universally agreed-upon standard. It varies based on geographical location and, to some extent, even the specific measuring tools used. This variation can lead to confusion and potential errors in recipes.
Understanding the US Tablespoon Standard
In the United States, a standard tablespoon is defined as exactly 14.7868 ml. However, for practical cooking purposes, it’s commonly rounded up to 15 ml. This rounding makes it easier to convert between tablespoons and other units of volume. Therefore, in the US, a tablespoon is not 20ml.
Exploring the UK and Australian Tablespoon Variance
The story changes slightly when we cross the Atlantic or head down under. In the United Kingdom and Australia, a tablespoon is traditionally defined as 17.7 ml. This is significantly larger than the US tablespoon.
The Metric Tablespoon: A Closer Look
Adding another layer of complexity, there’s the metric tablespoon. The metric system aims for simplicity, and in many contexts, a metric tablespoon is considered to be precisely 20 ml. This is often seen in international recipes or those that specifically state “metric tablespoon.”
Why Does This Discrepancy Exist?
The differences in tablespoon measurements can be attributed to historical reasons and the evolution of culinary standards in different regions. The US system is rooted in older English measurements, while the UK and Australia retained slightly different interpretations. The introduction of the metric system brought a more standardized approach, but its adoption varies across different countries and culinary practices.
The Impact of Standardized Measuring Tools
While historical definitions are interesting, the modern reality is that most commercially available measuring spoons are designed to reflect these different standards. A set of US measuring spoons will typically include a tablespoon measuring 15 ml, while sets from the UK or Australia might offer spoons closer to 17.7 ml. Metric tablespoon sets are less common, with cooks often relying on the 15 ml US standard or adjusting recipes accordingly.
Practical Implications for Cooking and Baking
The confusion surrounding tablespoon measurements can have real-world consequences in the kitchen. Inconsistent measurements can lead to dishes that are too salty, too sweet, or simply not balanced in flavor.
Adjusting Recipes Based on Location
If you’re using a recipe from a different country, it’s crucial to be aware of the potential differences in tablespoon measurements. A recipe calling for 2 tablespoons of soy sauce in the US might require slightly less if you’re using a UK tablespoon. This is especially important when dealing with ingredients that have a strong impact on the taste, such as salt, spices, and extracts.
The Importance of Accurate Measuring Tools
Using reliable and accurate measuring tools is essential for consistent results. Invest in a good set of measuring spoons and cups, and be sure to check their markings to ensure they align with the standard you’re using (US, UK, or metric). Digital kitchen scales are also invaluable for converting between volume and weight, providing even greater precision.
Converting Between Units
When faced with conflicting tablespoon measurements, it’s helpful to know how to convert between different units. Here’s a quick reference guide:
- US Tablespoon: Approximately 15 ml
- UK/Australian Tablespoon: Approximately 17.7 ml
- Metric Tablespoon: 20 ml
You can use online conversion tools or simply multiply or divide by the appropriate factors. For example, to convert 2 US tablespoons to milliliters, multiply 2 by 15, resulting in 30 ml.
When Precision Matters Most
While slight variations in some ingredients might not significantly affect the final dish, there are certain situations where precision is paramount.
Baking: A Realm of Precise Ratios
Baking is a science, and precise ingredient ratios are crucial for achieving the desired texture, rise, and flavor. When baking, it’s especially important to use accurate measurements, particularly for ingredients like baking powder, baking soda, and yeast. Even a small error in these ingredients can lead to a cake that doesn’t rise properly or cookies that are too flat.
Medication Dosage: Safety First
Outside of the kitchen, tablespoon measurements are sometimes used for administering liquid medications. In these cases, it’s absolutely essential to use a calibrated measuring spoon or syringe to ensure accurate dosage. Never use a standard kitchen tablespoon for measuring medication, as the variations in size can lead to underdosing or overdosing, which can have serious consequences.
High-Ratio Cakes: Achieving Perfect Texture
High-ratio cakes, characterized by a high proportion of sugar and fat to flour, demand accurate measurements to maintain their delicate structure. In these recipes, even small discrepancies can disrupt the balance and compromise the cake’s texture.
Practical Tips for Accurate Measurement
Mastering accurate measurements is a skill that develops over time with practice. Here are some tips to help you improve your measuring accuracy:
Leveling Dry Ingredients
When measuring dry ingredients like flour, sugar, or spices, always level off the measuring spoon or cup using a straight edge, such as a knife or spatula. Avoid packing the ingredient into the spoon, as this will result in an inaccurate measurement.
Measuring Liquids at Eye Level
When measuring liquids, use a liquid measuring cup with clear markings. Place the cup on a flat surface and bend down to eye level to ensure an accurate reading.
Spoon and Sweep Method
For dry ingredients, use a spoon to gently scoop the ingredient into the measuring cup or spoon, then sweep off the excess with a straight edge. This method helps to avoid compaction and ensures a more accurate measurement.
Using a Kitchen Scale
For the most accurate results, consider using a kitchen scale to measure ingredients by weight. Weight measurements are generally more precise than volume measurements, especially for dry ingredients.
The Future of Culinary Measurement
As technology continues to advance, we may see even more precise and standardized measurement tools emerge in the culinary world. Digital measuring devices, smart kitchen appliances, and online recipe platforms that automatically adjust measurements based on location could help to eliminate the confusion surrounding tablespoons and other units of volume.
Embracing Metrication
A wider adoption of the metric system in cooking and baking would greatly simplify measurements and reduce the potential for errors. The metric system’s inherent simplicity and consistency make it an ideal choice for culinary applications.
Standardized Measuring Tools
Efforts to standardize measuring tool sizes and markings across different regions could also help to eliminate confusion and promote greater accuracy in recipes.
Conclusion: Navigating the Tablespoon Maze
So, is a tablespoon 20ml? The answer is not a simple yes or no. It depends on whether you’re referring to a US tablespoon (approximately 15 ml), a UK/Australian tablespoon (approximately 17.7 ml), or a metric tablespoon (20 ml). Understanding these differences and using accurate measuring tools are essential for achieving consistent and successful results in your cooking and baking endeavors. Always double-check the source of your recipe and adjust your measurements accordingly. Ultimately, a little attention to detail can make a big difference in the final outcome of your culinary creations.

Is a Tablespoon Always Exactly 20ml?
The short answer is no, a tablespoon is not always exactly 20ml. While some culinary sources might round the measurement to 20ml for simplicity, the internationally recognized standard and the one most commonly used in recipe development defines a tablespoon as 15ml. This discrepancy can lead to slight inaccuracies in recipes, especially when precise measurements are crucial, such as in baking or medicinal preparations.
The origin of the tablespoon measurement can be traced back to varying sizes of spoons used historically. Over time, standardization efforts aimed to create a more uniform measurement, but differences persist across regions and recipe books. To avoid confusion, it is always best to check the specific tablespoon measurement used in a recipe and use measuring spoons designed for culinary purposes, rather than relying on household silverware.
Why Do Some Recipes List a Tablespoon as 20ml?
Some recipes, particularly older ones or those influenced by certain regional culinary traditions, might use a tablespoon measurement of 20ml. This is often a simplification for easier conversions or because that measurement was historically common in the region the recipe originated from. Rounding to 20ml can also be a means of reducing fractional measurements, making the recipe appear less intimidating to novice cooks.
However, relying on this measurement without verifying its origin can lead to inconsistencies in the final result. Culinary professionals and many modern recipes adhere to the standardized 15ml tablespoon to ensure accurate proportions and flavor profiles. It’s always a good practice to confirm the tablespoon measurement used in any recipe, particularly if precision is important to the success of the dish.
What is the Standard Milliliter Equivalent of a Tablespoon?
The standard milliliter equivalent of a tablespoon, as defined by most culinary and scientific sources, is 15ml. This measurement is widely adopted for recipe development, food labeling, and other applications where precise liquid volume is critical. Using a 15ml tablespoon ensures consistency when following recipes and helps achieve the intended results.
This standardization simplifies recipe scaling and allows cooks to accurately reproduce dishes across different locations. Measuring spoons, specifically designed for culinary use, are calibrated to this 15ml standard, making it easier to obtain accurate measurements. Therefore, when a recipe calls for a tablespoon, it is generally understood to mean 15ml unless otherwise specified.
How Can I Accurately Measure a Tablespoon of Liquid?
The most accurate way to measure a tablespoon of liquid is to use a set of standardized measuring spoons. These spoons are specifically calibrated to hold a precise volume of 15ml. Pour the liquid into the measuring spoon until it reaches the top without overflowing, ensuring a level measurement.
Avoid using household silverware as a substitute, as their capacity can vary significantly. To ensure the most accurate measurement, especially for ingredients like vanilla extract or baking powder, use a liquid measuring cup with tablespoon markings or a graduated cylinder for greater precision. This practice minimizes potential errors and contributes to more consistent results in your cooking.
Does a Level Tablespoon Matter?
Yes, a level tablespoon is crucial for accuracy, particularly when baking or using potent ingredients. A level measurement ensures that you are using the precise amount of the ingredient specified in the recipe, preventing imbalances that can affect the final product’s texture, flavor, or chemical reactions. Whether you are measuring liquids or solids, leveling is an essential step for achieving consistent outcomes.
To level a tablespoon of a solid ingredient, such as flour or sugar, fill the spoon generously and then use a straight edge, like the back of a knife, to scrape off the excess, creating a perfectly level surface. For liquids, pour the liquid into the spoon until it reaches the top, avoiding any overflowing. Precise leveling contributes significantly to predictable and successful recipe execution.
What’s the Difference Between a Tablespoon and a Teaspoon?
The primary difference between a tablespoon and a teaspoon lies in their volume. A tablespoon is significantly larger than a teaspoon. Specifically, one tablespoon is equal to three teaspoons. This is a fundamental conversion in culinary measurements and is essential to understand for accurate recipe execution.
Confusion between the two can lead to significant errors in taste, texture, and the overall success of a recipe. Therefore, always double-check which unit of measurement is being called for and use the appropriate measuring spoons. Mastering this distinction is a basic skill for any home cook or culinary professional.
How Does Ingredient Density Affect Tablespoon Measurement?
Ingredient density significantly affects how much of a particular ingredient fits into a tablespoon. A tablespoon of tightly packed brown sugar will weigh considerably more than a tablespoon of loosely scooped flour, even though they both occupy the same volume. This difference arises because different ingredients have different densities.
Therefore, it’s important to follow the recipe’s instructions regarding how to measure ingredients. Some recipes specify measurements by weight (grams or ounces), which is more accurate than volume (tablespoons or cups) because it eliminates the influence of ingredient density. If a recipe calls for a level tablespoon of flour, avoid packing it down, as this will result in using more flour than intended, potentially affecting the recipe’s outcome.
