Guides
The Volume Converter turns a single volume measurement into its equivalent across 16 units at once. Enter one value, choose the unit it is expressed in, and the tool instantly builds a table showing the same volume in liters, milliliters, cubic meters, US and Imperial cups/pints/quarts/gallons, and more.
Volume is one of the trickiest quantities to convert because the US and Imperial (UK) systems use the same unit names — cup, pint, gallon — for genuinely different amounts. A US gallon (3.785 L) is about 17% smaller than an Imperial gallon (4.546 L). This tool keeps the two systems clearly separate so a recipe or fuel figure never gets silently misconverted.
How to use it
- Type the amount you want to convert into the Amount box.
- Pick the unit that amount is in from the Unit list.
- Optionally set the Decimal precision (0 to 10 places) for how the results are rounded.
The results table updates automatically. Use the copy and download buttons to grab every conversion as CSV.

Is a US gallon the same as an Imperial gallon?
No. A US gallon is 3.785 liters, while an Imperial (UK) gallon is 4.546 liters — about 20% larger. Always check which gallon a source means, especially for fuel economy and cooking measurements.
How many milliliters are in a cup?
A US cup is 236.588 mL. The Imperial cup isn't listed separately since it's rarely used — modern Imperial recipes measure by pints and fluid ounces instead.
Why are cubic centimeter and milliliter listed as the same value?
They are the same by definition: 1 mL is exactly 1 cm³. Both names are kept because "cc" and "cm³" are standard in medicine and engineering while "mL" is standard in cooking and everyday use.
