How many tablespoons is 28 g is a common question when you’re trying to follow a recipe that lists ingredients by weight but your kitchen tools only measure volume. Because grams measure mass and tablespoons measure volume, the answer depends on the density of the substance you’re measuring. Below is a detailed guide that explains the concept, shows how to calculate the conversion for various everyday ingredients, and offers practical tips to ensure accuracy in your cooking and baking.
Understanding Weight vs. Volume
Before diving into numbers, it’s helpful to clarify why a direct conversion isn’t universal.
- Grams (g) quantify mass – how much matter is in an object.
- Tablespoons (tbsp) quantify volume – how much space that matter occupies.
Two substances with the same mass can occupy very different volumes if their densities differ. Even so, for example, 28 g of honey is far denser (and thus takes up less space) than 28 g of powdered sugar. That's why, the answer to “how many tablespoons is 28 g” changes with each ingredient.
General Conversion Formula
The relationship between mass, volume, and density is:
[ \text{Volume (tbsp)} = \frac{\text{Mass (g)}}{\text{Density (g / tbsp)}} ]
If you know the density of an ingredient expressed in grams per tablespoon, you can plug 28 g into the formula to get the volume. Many cooking references list densities as “grams per cup” or “grams per milliliter”; you can convert those to grams per tablespoon using the fact that 1 US tablespoon = 14.7868 mL (≈15 mL for quick estimates) That alone is useful..
Step‑by‑Step Calculation for Common Ingredients
Below is a step‑by‑step method you can follow for any ingredient, followed by pre‑calculated results for frequently used pantry staples.
1. Find the ingredient’s density
Look up the density in grams per milliliter (g/mL) or grams per cup. Reliable sources include USDA FoodData Central, baking textbooks, or reputable cooking websites But it adds up..
2. Convert density to grams per tablespoon
[ \text{Density (g / tbsp)} = \text{Density (g / mL)} \times 14.7868 ]
3. Apply the formula
[ \text{Tablespoons} = \frac{28}{\text{Density (g / tbsp)}} ]
4. Round to a practical measuring increment
Most measuring spoons are marked in ¼‑tbsp increments; round accordingly.

Scientific Explanation: Why Density Matters
Density is defined as mass per unit volume. In the kitchen, it tells you how tightly the molecules of a substance are packed.
- Water serves as the baseline because its density is close to 1 g/mL at 4 °C, making 1 mL ≈ 1 g. Because of this, 28 g of water ≈ 28 mL, which divides to about 1.89 tbsp.
- Oils are slightly less dense than water (≈0.92 g/mL), so the same mass occupies a bit more volume, yielding roughly 2 tbsp.
- Powdered ingredients like flour or cocoa have lots of air trapped between particles, lowering their bulk density to 0.4–0.6 g/mL. Hence, 28 g translates to a larger volume—often 3–4 tbsp.
- Sugars and syrups are denser due to tighter molecular packing and, in the case of honey, additional water‑binding sugars, resulting in smaller volumes for the same weight.
Understanding this principle helps you adjust recipes when you only have a scale or only have measuring spoons, and it explains why sifting flour (which reduces its density) can dramatically change the volume you need.
Practical Tips for Accurate Measurement
- Use a kitchen scale whenever possible – weighing eliminates guesswork entirely.
- When using spoons, level off – sweep a straight edge across the top of the spoon to remove excess.
- Consider the ingredient’s state – softened butter packs differently than cold butter; melted honey is denser than crystallized honey.
- Adjust for humidity – hygroscopic ingredients like flour and sugar can absorb moisture, slightly increasing their weight per volume.
- Create a personal conversion chart
