Cooking Measurement Converter
Convert teaspoons, tablespoons, cups, milliliters, and liters.
This cooking measurement converter switches between common recipe units - teaspoons, tablespoons, cups, milliliters, and liters - helping adapt recipes between US customary measurements and metric measurements used elsewhere.
Enter a measurement in any supported unit, and the calculator returns the equivalent in your chosen target unit.
Worked Calculation Examples
| Scenario | Result | Calculation Step |
|---|---|---|
| 3 tablespoons to milliliters | ≈44.4 mL | 3 × 14.79 mL ≈ 44.4 mL. |
| 2 cups to milliliters | ≈473.2 mL | 2 × 236.6 mL ≈ 473.2 mL. |
Key Cooking Conversion Factors
1 US tablespoon = 3 teaspoons = 14.79 mL. 1 US cup = 16 tablespoons = 236.6 mL. These relationships form the basis for most recipe unit conversions, though it's worth noting that a 'cup' can mean a genuinely different volume in different countries' measurement systems.
Why Recipe Conversion Isn't Always Purely Volumetric
For dry ingredients like flour, converting between volume (cups) and weight (grams) isn't purely mathematical, since ingredient density and how tightly it's packed affects the actual amount in a given volume - many bakers prefer weighing dry ingredients by grams specifically to avoid this inconsistency, especially for precise recipes.

Frequently Asked Questions
How many teaspoons are in a tablespoon?
3 teaspoons equal 1 tablespoon in US customary measurement.
How many milliliters are in a cup?
1 US cup equals approximately 236.6 milliliters, though this can vary slightly for cup definitions used in other countries.
Why do bakers sometimes recommend weighing flour instead of using cup measurements?
Flour's density varies depending on how it's scooped and packed, so a cup measurement can vary noticeably in actual flour weight between different people measuring the same recipe - weighing in grams gives a more consistent, repeatable result.
How do I use this cooking measurement converter?
Enter the known values, review the units or settings, and the calculator updates the result instantly. The formula and example on this page show how the answer is produced.
What does the Cooking Measurement Converter calculate?
Convert teaspoons, tablespoons, cups, milliliters, and liters. It is designed for fast browser-based calculations without sign-up, downloads, or manual spreadsheet setup.
What formula does this cooking measurement use?
The formula is: target = source * conversion factor. The US customary cup, tablespoon, and teaspoon measurements used in American recipes trace back to informal 19th-century household measuring conventions, only loosely standardized compared to the precisely defined metric measurements (milliliters, liters) used in most other countries' recipes - this historical difference is exactly why converting a recipe between US and metric measurements requires a genuine unit conversion rather than a simple relabeling.
