Tablespoons to Grams Converter
Accurate tablespoon to gram conversions for 14 common ingredients — or enter any ingredient's density for a custom result. Different ingredients weigh differently; density matters.
✓ 14 Ingredients✓ Custom Density✓ Bidirectional✓ Formula Shown
A tablespoon of flour weighs 7.8g. A tablespoon of honey weighs 21.25g. A tablespoon of salt weighs 18g. Density changes everything — the generic "15g per tablespoon" rule is only accurate for water and thin liquids. This converter uses verified per-ingredient weights, and lets you enter a custom density for any ingredient not in the list.

The Formula: How Tablespoons Convert to Grams
The conversion formula is: grams = tablespoons × 14.787 × density (g/mL)
Where 14.787 mL is the volume of 1 US tablespoon (14.787 mL exactly). Density is the ingredient's weight per mL. Examples:
Water density = 1.0 g/mL → 1 tbsp = 14.787 × 1.0 ≈ 14.8g
This is why the "15g per tablespoon" rule works for water but not for flour (which is nearly half the weight). The Custom Ingredient option lets you enter any density value — useful for specialty ingredients like tahini, miso paste, almond butter, and more.
Frequently Asked Questions
How many grams is 1 tablespoon of flour?
1 tablespoon of all-purpose flour weighs approximately 7.8 grams. Bread flour is slightly heavier at 8.1g, almond flour lighter at 6.0g. These values assume the flour is spooned into the tablespoon and leveled — not packed or scooped directly.
How many grams is 1 tablespoon of sugar?
1 tablespoon of white granulated sugar = 12.5g. Brown sugar (lightly packed) = 13.75g. Powdered/icing sugar = 7.5g (it's much lighter due to fine texture and cornstarch). Raw turbinado sugar ≈ 12g.
How many grams is 1 tablespoon of butter?
1 tablespoon of butter = 14.2 grams. A US stick of butter (8 tablespoons) = 113.6g ≈ 114g. European butter has a slightly higher fat content but weighs the same per tablespoon.
How many grams is 1 tablespoon of honey?
1 tablespoon of honey = 21.25 grams — one of the heaviest ingredients per tablespoon because honey is significantly denser than water. This is why substituting honey for sugar by volume (tablespoons) will make your recipe much sweeter and heavier.
Is 1 tablespoon always 15 grams?
Only for water and very thin liquids. 15g per tablespoon is a rough average that is accurate for water (14.8g) and milk (15g), but not for most other ingredients. Flour is 7.8g, honey is 21.25g, salt is 18g. Always use ingredient-specific values for accurate baking results.
How do I convert an ingredient not in the list?
Use the Custom Ingredient option in the pill selector. Enter the ingredient name and its density in grams per tablespoon. You can find density values from the USDA FoodData Central database or from the manufacturer's nutrition label (which lists serving size in grams and tablespoons). Example: if a label says "1 tbsp (16g)", enter 16 as the g/tbsp value.
How many grams is 1 tablespoon of salt?
1 tablespoon of fine table salt = 18 grams. Coarse kosher salt weighs less (10–14g per tablespoon) due to larger crystal size and more air between grains. Always check which type your recipe specifies — the difference matters significantly for seasoning.
About This Converter
Ingredient weights sourced from USDA FoodData Central and verified by our kitchen team. Values represent the US tablespoon (14.787 mL). Flour values assume spooned-and-leveled; brown sugar assumes lightly packed. Custom ingredient mode accepts any user-supplied density. All calculations run in your browser.
