Free kitchen calculator
Convert teaspoons to tablespoons instantly. Use 3 teaspoons per tablespoon, plus metric and US spoon references for cooking. The teaspoons to tablespoons result updates as you type, works offline, and is built for real recipe work on a phone or laptop.
Use this when scaling spice, salt, extract, yeast or leavening amounts. Three teaspoons make one tablespoon, but the calculator also displays readable kitchen fractions.
The result is a spoon ratio. For salt, yeast, baking soda and hot spices, keep rounding conservative and adjust after testing.
| Amount | Result |
|---|---|
| 1 tsp | 1/3 tbsp |
| 1.5 tsp | 1/2 tbsp |
| 3 tsp | 1 tbsp |
| 6 tsp | 2 tbsp |
| 9 tsp | 3 tbsp |
| 12 tsp | 4 tbsp |
| 24 tsp | 8 tbsp |
| 48 tsp | 16 tbsp |
The calculator keeps the arithmetic visible because kitchen conversions should be checkable, not mysterious.
Search the table, then tap a heading to sort. Values are rounded only in the display; calculations use the constants embedded in the page.
This page is intentionally deterministic: no AI model, tracking script, or remote lookup is used for the calculation. The values are hardcoded from kitchen reference constants and public food-safety or nutrition references so the result is repeatable.
Enter the amount, choose the relevant unit or ingredient, and read the live result. The calculator uses fixed kitchen constants and, when needed, ingredient density so baking conversions are more useful than a plain volume swap.
It is accurate for the reference values shown on the page. Flour, sugar, butter and liquids do not weigh the same, so ingredient-based tools use density data rather than assuming every cup is water.
Yes. You can type decimals, simple fractions, mixed fractions, and common Unicode fractions such as ½ or ¼. This is useful when copying amounts directly from a recipe card.
Yes. The calculator is a standalone HTML file with hardcoded data and no API calls. Once the page is loaded, calculations happen in your browser.
US customary cup is the default where a cup unit is needed. You can switch to US legal, metric, UK imperial, or Japanese cup sizes on tools where cup size changes the math.
A cup is volume, while grams and ounces are weight. A cup of honey is much heavier than a cup of rolled oats, so density is the difference between a reliable bake and a guess.
Yes. Use the Copy result button after the live result updates. The copied text includes the main answer and the key setting used.
For bread, pizza dough, pastry and repeatable baking, a scale is best. Volume measures are convenient, but grams remove packing, scooping and cup-size differences.
Yes. The page footer cites King Arthur Baking for baking weights, USDA FoodData Central and FSIS for food data and temperatures, and FDA or ACOG where caffeine limits are discussed.
Yes. The print stylesheet hides controls and keeps the result, formula and reference chart so you can keep a clean kitchen copy.
