How to Convert Tablespoons to Grams

A tablespoon is a unit of volume — in the US, it equals exactly 15 mL. But a tablespoon of honey and a tablespoon of flour do not weigh the same. To convert tablespoons to grams, you need to know how dense the ingredient is. The formula is simple:

Grams = Tablespoons × Grams per Tablespoon

For example, 1 tablespoon of all-purpose flour = 1 × 7.8 = 7.8 grams. 3 tablespoons of honey = 3 × 21 = 63 grams. This calculator uses ingredient-specific density data for 48 common baking and cooking ingredients so you always get an accurate result.

Why Tablespoon Weight Varies by Ingredient

Density is the key. Honey is a thick liquid with tightly packed sugar molecules — it weighs 21 grams per tablespoon. All-purpose flour is a fine powder with plenty of air trapped between particles — it weighs only 7.8 grams per tablespoon. Vegetable oil sits in the middle at 13.6 grams per tablespoon.

This is why using a generic "1 tablespoon = X grams" conversion will give you the wrong answer. The correct weight depends entirely on what you are measuring. Our calculator uses verified, ingredient-specific data so your baked goods come out right every time.

Tablespoon Reference for Common Ingredients

Ingredient	1 tbsp (grams)	2 tbsp (grams)	4 tbsp (grams)
All-Purpose Flour	7.8 g	15.6 g	31.2 g
White Sugar	12.5 g	25 g	50 g
Butter	14.2 g	28.4 g	56.8 g
Honey	21 g	42 g	84 g
Cocoa Powder	5.3 g	10.6 g	21.2 g
Olive Oil	13.5 g	27 g	54 g
Maple Syrup	20.1 g	40.2 g	80.4 g
Baking Powder	12 g	24 g	48 g

Tablespoon to Cup Conversions

When scaling recipes, it helps to know how tablespoons relate to cups. In US cooking:

1 cup = 16 tablespoons
¾ cup = 12 tablespoons
½ cup = 8 tablespoons
¼ cup = 4 tablespoons
⅛ cup = 2 tablespoons
1 tablespoon = 3 teaspoons

So if a recipe calls for ½ cup of sugar, that is 8 tablespoons — or 100 grams of white sugar. Use the cup-equivalent output in the results above to quickly cross-reference these conversions.

How to Measure Tablespoons Accurately

For the most accurate measurements, use a dedicated set of measuring spoons rather than an everyday cutlery tablespoon. Cutlery spoons vary in size and can hold anywhere from 7 mL to 20 mL — well outside the standard 15 mL. For dry ingredients, fill the spoon and level it with the straight edge of a knife. For sticky liquids like honey or maple syrup, spray the spoon lightly with cooking spray first; the ingredient will slide out cleanly without sticking.

If precision is important — particularly in baking — use a digital kitchen scale. Even small differences in flour or baking powder weight can affect the final texture of cakes and bread. This calculator lets you plan ahead by giving you the exact gram weight so you can weigh directly.

UK vs US Tablespoon

This calculator uses the US tablespoon (15 mL), which is the most widely used standard worldwide. The UK tablespoon is also 15 mL in modern usage, so results are the same for both. Australian tablespoons are 20 mL — if you are following an Australian recipe, multiply the result by 1.33 to get the correct gram weight for Australian tablespoons.

Frequently Asked Questions

1 tablespoon of all-purpose flour weighs approximately 7.8 grams. Bread flour is slightly heavier at 8.1 g/tbsp, while cake flour is lighter at 7.1 g/tbsp. Always use the specific flour type for the most accurate result.

1 tablespoon of butter weighs 14.2 grams. This is a standard US tablespoon (roughly 15 mL). Most butter sticks in the US are marked with tablespoon lines for easy measuring.

1 tablespoon of honey weighs approximately 21 grams, making it significantly heavier than most dry ingredients. Honey is very dense — about 1.42 g/mL — which is why a tablespoon of honey weighs so much more than a tablespoon of flour.

No. A US tablespoon is always 15 mL by volume, but the gram weight depends entirely on the density of the ingredient. Water weighs 14.8 g per tablespoon, honey weighs 21 g, and flour weighs only 7.8 g. Always convert by ingredient, not by a universal tablespoon-to-gram ratio.

There are exactly 3 teaspoons in 1 tablespoon. This is a fixed volume relationship: 1 tbsp = 3 tsp = 15 mL. It applies in both US and metric cooking measurements.

There are 16 tablespoons in 1 US cup (240 mL). This means ½ cup = 8 tbsp, ¼ cup = 4 tbsp, and 1 tbsp = 1/16 cup. Knowing this relationship helps when scaling recipes up or down.

For dry ingredients, spoon the ingredient into the tablespoon measure and level it off with a straight edge. Do not scoop directly from the bag as this compresses the ingredient and adds 10–20% extra weight. For liquids and sticky ingredients like honey, use a slightly greased tablespoon for easy release.

Oil and flour have very different densities. A tablespoon of vegetable oil weighs 13.6 grams because oil is denser than air-fluffed flour, which weighs only 7.8 grams per tablespoon. Density is the mass per unit volume — ingredients with more tightly packed molecules weigh more for the same volume.
