The Definitive Answer to Mayonnaise Measurements
When it comes to baking and accurate nutrition tracking, moving beyond volume-based measurements like tablespoons to weight-based grams is a game-changer. For the popular condiment, the question of how many grams is 2 tablespoons of mayonnaise has a clear and widely accepted answer: it is 28 grams. This conversion is based on the average density of standard mayonnaise and serves as a reliable guide for home cooks and nutrition-conscious individuals alike.
Why Volume Measurements Are Not Always Accurate
Using a tablespoon to measure mayonnaise seems straightforward, but it can introduce significant inaccuracies. Unlike water, mayonnaise is a viscous, semi-solid substance. The amount you get in a tablespoon can vary based on several factors:
- How tightly packed it is: Scooping a tablespoon of thick mayonnaise and leveling it off can result in a different amount than a loosely scooped tablespoon.
- The specific brand: Different brands of mayonnaise and variations like 'light' or 'traditional' have slightly different densities. Light mayonnaise, for instance, has a higher water content, making it less dense than traditional varieties.
- The shape of your spoon: While standardized, the depth and curvature of different tablespoons can differ slightly, leading to small variations in volume.
This is why for precision-dependent activities like baking, or when adhering to specific dietary requirements, weight is the gold standard. A kitchen scale eliminates all these variables, providing an exact and repeatable measurement every time.
Comparing Traditional vs. Light Mayonnaise
Understanding the slight differences in density between mayonnaise types helps explain why conversions can vary. The core ingredients—oil, egg yolk, and an acid like vinegar—are emulsified to create the condiment. Light versions are formulated with less fat and more water, which affects their density.
- Traditional Mayonnaise: With a density of approximately 0.91 g/cm³, traditional mayo weighs a bit less per unit of volume than water.
- Light Mayonnaise: Featuring a higher water content, the density of light mayo is closer to that of water, around 1 g/cm³.
For most practical purposes, the difference is negligible for a small quantity like two tablespoons. The 28-gram figure is a solid benchmark for general-purpose, full-fat mayonnaise. However, in recipes where precision is paramount, it is always best to check the nutritional information on the product's label, which typically lists the gram weight for a serving size.
How to Accurately Measure Mayonnaise by Weight
To ensure your measurements are always consistent, follow these steps using a digital kitchen scale:
- Place a bowl or container on your digital scale.
- Turn on the scale and tare it (zero it out) to eliminate the container's weight.
- Scoop the mayonnaise directly into the bowl.
- Add or remove mayonnaise until the scale displays the target weight of 28 grams.
This method is particularly useful when you need to measure other sticky, semi-liquid ingredients like peanut butter or honey, which also pose challenges for volume-based measuring. For example, a single tablespoon of honey can weigh more than 20 grams, showcasing how different food densities require different conversions.
Table: Volume vs. Weight Measurement for Mayonnaise
| Feature | Volume Measurement (Tablespoons) | Weight Measurement (Grams) |
|---|---|---|
| Equipment | Measuring spoons | Digital kitchen scale |
| Accuracy | Prone to variations based on scooping technique and product density | Highly accurate and repeatable |
| Consistency | Inconsistent results, especially between different products | Extremely consistent, yielding the same result every time |
| Ease of Use | Fast and convenient for quick, rough measurements | Slower initially but simple once you're used to the scale |
| Best For | Everyday cooking and approximate recipe needs | Baking, strict diets, and professional food preparation |
| Cleanliness | Messy cleanup with sticky mayo on spoons | Container on the scale can be easily scraped clean |
Benefits of Measuring by Weight
Beyond the obvious benefit of accuracy, weighing your ingredients offers several advantages:
- Better Recipe Results: Consistent measurements lead to more reliable outcomes, especially in delicate recipes where ingredient ratios are critical.
- Easier Calorie Tracking: For those counting calories or macros, using an accurate gram weight is essential for logging food intake correctly. The difference of a few grams can add up over time.
- Less Cleanup: As demonstrated in the table, using a scale with a single bowl can be tidier than washing multiple sticky measuring spoons.
- Flexibility: Once you know the density, you can easily scale recipes up or down by weight, simplifying adjustments for different batch sizes.
Conclusion
To answer the question definitively, how many grams is 2 tablespoons of mayonnaise is 28 grams. However, the true takeaway is the superiority of weighing over volume measurement for consistency and accuracy. While using a tablespoon is convenient for quick, casual cooking, investing in a digital kitchen scale provides a level of precision that benefits both your recipes and your nutritional goals. For perfect results every time, let your kitchen scale be your guide.

Frequently Asked Questions
Why does the conversion for mayonnaise differ from water?
Mayonnaise is an emulsion of oil and egg yolks, giving it a lower density than water. Because of this, equal volumes of mayonnaise and water will not have the same mass, making volume measurements unreliable for conversion.
How many tablespoons are in 28 grams of mayonnaise?
Approximately 2 tablespoons of mayonnaise are equivalent to 28 grams, according to standard nutritional data.
Is the weight of 2 tablespoons the same for traditional and light mayonnaise?
No, because light mayonnaise has a higher water content and lower fat, its density is slightly different from traditional mayonnaise. The 28-gram conversion is generally based on standard, full-fat versions, but the difference for a small amount is usually minimal.
What is a good way to measure mayonnaise without a scale?
If you don't have a scale, you can use a plunger-style adjustable measuring cup for sticky ingredients, or simply be mindful to scoop and level off your tablespoon consistently to minimize variation.
What is the weight of one tablespoon of mayonnaise?
Based on the 28-gram figure for two tablespoons, a single tablespoon of mayonnaise is approximately 14 grams.
How does mayonnaise compare to other ingredients by weight?
Many ingredients have different conversions. For example, a tablespoon of honey (around 21 grams) is heavier than a tablespoon of mayonnaise (14 grams), while a tablespoon of water is about 15 grams.
Is it better to measure mayonnaise by weight or by volume?
Measuring mayonnaise by weight (grams) is always more accurate and consistent, especially for recipes that require precision or for tracking nutritional information. Measuring by volume (tablespoons) is quicker but less reliable.
What are some other conversions for mayonnaise?
- 1 tablespoon = approx. 14 grams
- 1 cup = approx. 220-225 grams (depending on density)
- 1/2 cup = approx. 110-113 grams
Does the temperature of the mayonnaise affect its weight?
The temperature can slightly affect its density and viscosity, but for typical kitchen temperatures, the difference in weight for a small amount like 2 tablespoons is negligible.
Can I use nutritional information on the jar for conversion?
Yes, checking the nutritional label is the most accurate way to confirm conversions for the specific product you are using. Labels typically provide the gram weight for a specified serving size.
