Cooking Measurement Converter

Convert between common cooking measurements like cups, tablespoons, teaspoons, fluid ounces, grams, and milliliters. Perfect for following recipes from different countries or scaling recipes up and down.

Updated June 2026 · How this works

How It Works
The formula, explained simply

The cooking measurement converter works by using standardized conversion factors between different units of measurement commonly used in recipes. When you enter an amount and select your source and target units, the calculator applies the appropriate mathematical conversion to give you the equivalent measurement.

For volume conversions, the tool uses the US customary system where 1 cup equals 236.588 milliliters, 1 tablespoon equals 14.787 milliliters, and 1 teaspoon equals 4.929 milliliters. These precise conversions ensure accuracy when following international recipes or scaling ingredients.

Weight conversions use standard factors where 1 ounce equals 28.35 grams and 1 pound equals 453.6 grams. The cooking measurement converter also handles mixed conversions between volume and weight units using average ingredient densities, making it practical for real kitchen use.

The tool automatically determines whether you're converting between volume units (cups, milliliters), weight units (grams, ounces), or across different measurement types, applying the correct conversion method for accurate results every time.

When To Use This
Right tool, right situation

Use the cooking measurement converter when following international recipes that use different measurement systems than you're familiar with. This is especially helpful when American recipes call for cups and European recipes use grams and milliliters.

The tool is invaluable for scaling recipes up or down. Whether you're cooking for a larger group or want to make a smaller batch, converting measurements accurately ensures your dish maintains the right proportions and flavors.

Professional bakers and serious home cooks often prefer weight measurements over volume because they're more accurate and consistent. Use this converter to translate volume-based recipes into weight measurements for better results, especially in baking where precision matters most.

Common Mistakes
Why results sometimes look wrong

Common mistakes when converting cooking measurements include mixing up fluid ounces with weight ounces, which measure completely different properties. Always verify whether a recipe calls for volume or weight measurements.

Another frequent error is assuming all ingredients have the same density. A cup of flour weighs much less than a cup of sugar or butter. While our converter uses average conversions that work for most ingredients, professional baking often requires ingredient-specific conversions for precision.

Rounding errors can accumulate when making multiple conversions. It's better to convert directly from your source unit to your target unit rather than going through intermediate conversions. Also, be aware that some older recipes use Imperial measurements that differ slightly from US customary units.

The Math
Worked examples and deeper derivation

Cooking measurement conversions rely on fixed ratios between different units. The mathematical foundation uses these key relationships:

**Volume Conversions:** 1 US cup = 236.588 milliliters 1 tablespoon = 14.787 milliliters 1 teaspoon = 4.929 milliliters 1 fluid ounce = 29.574 milliliters

**Weight Conversions:** 1 ounce = 28.35 grams 1 pound = 453.6 grams 1 kilogram = 1000 grams

**Volume-to-Weight Approximations:** The calculator uses average ingredient densities for mixed conversions. For example, 1 cup of all-purpose flour ≈ 128 grams, while 1 cup of water ≈ 237 grams (nearly equal to its milliliter volume).

Converting Cups to Milliliters
1 cup to milliliters
1 US cup equals 236.588 milliliters, which is the standard conversion used in most recipes when converting between metric and imperial measurements.
Converting Tablespoons to Teaspoons
2 tablespoons to teaspoons
2 tablespoons equals 6 teaspoons since there are 3 teaspoons in every tablespoon. This is useful when you don't have the right measuring spoon size.
Converting Grams to Ounces
250 grams to ounces
250 grams equals approximately 8.82 ounces. This conversion is helpful when following European recipes that use metric measurements.

Common questions

How do I convert cups to grams for baking?
Converting cups to grams depends on the ingredient. For all-purpose flour, 1 cup equals about 128 grams. For sugar, 1 cup equals about 200 grams. Our cooking measurement converter uses average conversions that work well for most common ingredients.
What is the difference between fluid ounces and weight ounces?
Fluid ounces measure volume (like milliliters), while weight ounces measure mass (like grams). 1 fluid ounce equals about 29.57 milliliters, but 1 weight ounce equals about 28.35 grams. The cooking measurement converter handles both types appropriately.
How many tablespoons are in a cup?
There are 16 tablespoons in 1 US cup. This is a fundamental cooking conversion that's useful for scaling recipes up or down. You can also remember that 1 cup equals 48 teaspoons since there are 3 teaspoons per tablespoon.
