tbsp to Grams vs tsp to Grams Converter
A tablespoon and a teaspoon are both volumes; a gram is a mass. These two converters do the same job at two different spoon sizes: take a US spoon volume, convert it to milliliters, multiply by an ingredient density, and report grams. The tbsp to grams page is anchored on the US tablespoon of 14.78676478125 mL, and the tsp to grams page on the US teaspoon of 4.92892159375 mL — exactly one third of the tablespoon volume. The choice between them is mostly about which spoon your recipe actually names.
Because both calculators are density-based, neither pretends that one universal grams-per-spoon number works for every ingredient. Water, flour, sugar, butter, salt, and honey pack very different masses into the same spoon, and each page carries presets plus a custom-density entry so you can convert ingredients not on the list.
What each calculator does
The tbsp to grams converter multiplies tablespoons by 14.78676478125 to get milliliters, then applies the selected density in grams per milliliter. Its presets are water at 1.000 g/mL, all-purpose flour at 0.530 g/mL, granulated sugar at 0.850 g/mL, butter at 0.911 g/mL, and table salt at 1.200 g/mL. The article warns that a metric tablespoon (15 mL) and an imperial tablespoon differ from the US value, and that a level tablespoon is assumed rather than a heaped one.
The tsp to grams converter multiplies US teaspoons by 4.92892159375 to get milliliters, then applies density. Its presets are water at 1.000 g/mL, granulated sugar at 0.845 g/mL, table salt at 1.217 g/mL, all-purpose flour at 0.529 g/mL, honey at 1.420 g/mL, vegetable oil at 0.920 g/mL, and butter at 0.959 g/mL, with a custom g/mL option for anything else.
Side-by-side comparison
| Feature | tbsp to grams converter | tsp to grams converter |
|---|---|---|
| Spoon size | US tablespoon = 14.78676478125 mL | US teaspoon = 4.92892159375 mL |
| Formula | tbsp × 14.78676478125 × density | tsp × 4.92892159375 × density |
| Presets | Water, flour, sugar, butter, salt | Water, sugar, salt, flour, honey, oil, butter |
| Custom density | Yes | Yes |
| Spoon definition | US customary, level | US customary, level |
| Precision | Density-based estimate | Density-based estimate |
When to use which
Use the tbsp to grams converter when the recipe or label is written in tablespoons — typical for oils, nut butters, and larger ingredient amounts. Use the tsp to grams converter when the source is in teaspoons — typical for spices, salt, baking powder, and small quantities where a fraction of a gram matters. If a recipe mixes both spoons, you will likely touch both pages, and the numbers will line up only approximately: three teaspoons of volume equal one tablespoon, but the pages’ preset densities for the same named ingredient differ slightly, so scale-aware rounding is the honest way to compare.
Whichever page you use, remember the shared caveat: these are estimates. If the ingredient was sifted versus packed, or the spoon was heaped versus level, the real mass differs from the displayed grams. For repeatable baking, weigh directly.
