Recipes can describe the same liquid quantity in millilitres, cups, tablespoons, fluid ounces or several other units. The calculation becomes more confusing when cup and spoon sizes also vary between measurement systems. This converter puts the common cooking volume units in one place and lets you choose the kitchen standard that matches the recipe you are using.
The converter supports teaspoons, tablespoons, cups, fluid ounces, millilitres, litres, pints, quarts and gallons. The metric setting uses a 250 ml cup, 15 ml tablespoon and 5 ml teaspoon. The US customary setting uses a cup of about 236.6 ml, a tablespoon of about 14.79 ml and a teaspoon of about 4.93 ml.
Volume Converter
Convert common cooking volumes and choose the cup standard used by your recipe.
Fluid ounces, pints, quarts and gallons use US customary liquid values.
How to use the converter
- Enter the volume from your recipe.
- Choose the starting unit.
- Choose the target unit.
- Select the metric or US kitchen standard.
- Convert the amount.
- Use Swap when you want to reverse the conversion.
- Copy the result if you need it while cooking.
Fluid ounces, pints, quarts and gallons in this calculator use US customary liquid values. That distinction matters because a US pint and an imperial UK pint are not the same size. If a recipe specifically uses imperial pints or gallons, do not assume the US value is interchangeable.
This is a volume converter. It does not convert a cup of flour into grams because that calculation depends on ingredient density. Use the Ingredient Conversion Calculator when you need to move between volume and weight.

Frequently Asked Questions
How many millilitres are in one cup?
This tool uses 250 ml for a metric cup and approximately 236.6 ml for a US customary cup.
Can I convert teaspoons to millilitres?
Yes. The result follows the metric or US spoon standard you select.
Does the calculator support litres and gallons?
Yes. Both are included along with millilitres, cups, pints and quarts.
What kind of pint does the converter use?
It uses the US customary liquid pint of about 473.18 ml.
Is a UK imperial pint the same as a US pint?
No. An imperial pint is larger, so check the recipe’s measurement system before converting.
Can I convert cups to grams with this tool?
No. Cups measure volume and grams measure weight. Use the Ingredient Conversion Calculator for ingredient-specific estimates.
Why does the tool offer two cup standards?
A metric cup and a US customary cup have different volumes. Choosing the right standard helps avoid cumulative errors in recipes with several cups.
Does the calculator save my values?
No. The conversion happens in your browser and the plugin does not store your entries.
