A tablespoon measures volume; a gram measures weight — converting between them depends on what’s filling the tablespoon.
How it works
Multiplying tablespoons by the exact US tablespoon volume (14.79 mL) and then by the ingredient’s density (grams per mL) gives the weight in grams. The default density is water’s.
What this does not include
This does not include a built-in ingredient density table — for baking-specific ingredients like flour, sugar, or butter, check this site’s baking-ingredient-weight-converter, which has those densities built in by cup.
How to use this calculator
- Enter the tablespoons and the ingredient’s density (defaults to water).
Frequently asked questions
Why is a tablespoon’s weight different for every ingredient?
Because a tablespoon is a fixed *volume*, and different substances pack different amounts of mass into that same volume — honey is much denser than flour, for example.
How many teaspoons are in a tablespoon?
Exactly 3 — the US tablespoon and teaspoon are defined with that exact ratio.
Is a UK tablespoon the same size as a US tablespoon?
No — a UK/metric tablespoon is commonly 15 mL, slightly larger than the US tablespoon’s 14.79 mL used here.
