What it is
The Cooking Measurement Converter turns any kitchen volume into another — cups, tablespoons (tbsp), teaspoons (tsp), fluid ounces (fl oz) and milliliters (mL). It uses US customary volume equivalents, the standard found in most American recipes and measuring cups.
How to use it
Enter the amount, pick the unit you have ("From unit"), and the unit you want ("To unit"). The calculator first converts your amount into milliliters, then into the target unit. You always also see the milliliter equivalent so you can switch between metric and imperial cookware.
The formula explained
Every unit has a fixed milliliter value: 1 cup = 236.588 mL, 1 tbsp = 14.7868 mL, 1 tsp = 4.92892 mL, 1 fl oz = 29.5735 mL, and 1 mL = 1 mL. To convert, multiply the amount by the source factor to get milliliters, then divide by the target factor:
$$\text{result} = \frac{\text{value} \times f_{\text{from}}}{f_{\text{to}}}$$
Worked example
Convert 2 cups to tablespoons. First, \(2 \times 236.588 = 473.176\) mL. Then divide by the tablespoon factor: $$473.176 \div 14.7868 \approx 31.9998 \text{ tbsp}$$ — essentially 32 tablespoons per 2 cups, which matches the kitchen rule of 16 tbsp per cup.
FAQ
Are these US or metric units? The cup, tablespoon, teaspoon and fluid ounce values are US customary. Australian and UK measures differ slightly (e.g. an Australian tablespoon is 20 mL).
Why is 2 cups to tbsp not exactly 32? Rounding of the defined mL constants gives 31.9998, which rounds to 32 in practice.
Can I convert mL back to cups? Yes — set "From unit" to milliliters and "To unit" to cups.
