Grams to Tablespoons Calculator
Convert grams (mass) to US tablespoons (volume) for any cooking ingredient. Choose an ingredient to get its density automatically, or enter a custom value.

How does this calculator work?
tbsp = grams ÷ density (g/mL) ÷ 14.787. One US tablespoon = 3 tsp = 0.5 fl oz ≈ 14.79 mL. Select an ingredient to apply its bulk density automatically. 15 g of flour ≈ 1.7 tbsp; 15 g of water ≈ 1.01 tbsp; 15 g of honey ≈ 0.71 tbsp.
Formula
How this is calculated
Grams are a unit of mass and tablespoons are a unit of volume, so the ingredient's density bridges the two. The conversion works in two steps: grams divided by the ingredient's density in g/mL gives milliliters, then milliliters divided by 14.7868 (the volume of one US tablespoon) gives tablespoons.
Density varies widely between ingredients: water is 1.000 g/mL, all-purpose flour packs to about 0.593 g/mL, honey to 1.420 g/mL, and baking soda to about 0.690 g/mL. These standard bulk-density values assume normal scooping — sifting or packing an ingredient will shift the actual density. The "Custom ingredient" option lets you enter any density you know from a label or reference source.
One US tablespoon equals 3 teaspoons, 0.5 fluid ounces, or about 14.79 mL. The calculator also outputs equivalent teaspoons, fluid ounces, and cups so you can use whichever unit your recipe or measuring set calls for. All values are US customary; UK tablespoons (15 mL) and Australian tablespoons (20 mL) differ slightly.
Frequently asked questions
One tablespoon always holds 14.79 mL, but how many grams that is depends on the density of the ingredient. One tablespoon of water weighs about 14.8 g, one tablespoon of flour weighs about 8.8 g, and one tablespoon of honey weighs about 21 g.
Select "Custom ingredient" and enter the density in g/mL. You can find the density on nutritional databases, manufacturer data sheets, or by weighing a known volume of the ingredient. Divide the weight in grams by the volume in mL to get the density.
These are US tablespoons (14.787 mL each). A UK/metric tablespoon is 15 mL and an Australian tablespoon is 20 mL. The difference is small for most recipes but can matter for precise baking; verify which standard your recipe uses.
