Tablespoons to Grams Converter

Use this conversion when a recipe gives volume but your scale or package uses weight. The ingredient matters because equal tablespoon volumes can have different masses. Treat preset densities as cooking estimates, not as nutrition targets, supplement doses, or medical guidance.

Because honey is denser. A US tablespoon is approximately 14.79 mL, but the mass inside depends on density. At the calculator's estimates, that volume holds about 21 g of honey or 13.6 g of olive oil.

One US tablespoon is exactly 14.78676478125 mL. The shorter values 14.7867648 mL and 14.79 mL are approximations. The modern UK metric tablespoon is exactly 15 mL, and the Australian tablespoon is exactly 20 mL.

Because the air between flour particles compresses when you pack the spoon, and packing changes the mass-per-volume. Sifted all-purpose flour falls to about 0.529 g/mL, so 1 tbsp holds about 7.82 g. The same flour packed into the spoon by dipping straight into the bag and leveling rises to about 0.59 g/mL and 8.72 g per tbsp. That is an 11.5 percent swing for the same ingredient, the same spoon, and the same brand, just from technique. The drift compounds across a recipe: 12 tbsp of flour (about 3/4 cup) lands at 94 g sifted vs 105 g packed, an 11 g gap that is enough to dry out cookies, sink a cake, or toughen biscuits. The fix is a kitchen scale: weigh the flour and skip the spoon count entirely. This calculator exposes both flour-sifted and flour-packed presets so you can match whichever convention the recipe was written in.

Roughly 5 to 25 percent per ingredient, and it stacks. A 1 g resolution kitchen scale (about 15 to 25 USD) measures flour, sugar, and butter within 1 percent at the gram range bakers actually use (10 g and up). A tablespoon-measured ingredient drifts about 5 percent on liquids (honey, oil, milk), 10 to 15 percent on granular sugars and salt (depends on how flat the level is), and 15 to 25 percent on flours and powdered sugar (the packing variance). King Arthur Baking, Bread Bakers Guild of America, and Serious Eats all switched to gram-first recipes in the 2010s for that reason, especially for sourdough hydration (where a 5 percent water swing changes loaf structure visibly). The practical workflow is to keep the scale on the counter, set the bowl on it, hit tare, and add ingredients straight in without dirtying a measuring spoon. For everyday cooking (soups, marinades, stir-fries) tablespoons are still fine because a 10 percent variance does not change the dish.
