About Volume Converter

Volume units appear in recipes, product labels, storage and schoolwork. Select the correct system and convert the value, while checking whether a recipe means US or another regional cup measure.

How to use Volume Converter

  1. Enter the numeric volume.
  2. Choose the starting unit, such as liters or US cups.
  3. Choose the target unit.
  4. Select Convert and read the equivalent.
  5. Use Swap units to change the direction of conversion.

Recipes, tanks and labels

For cooking, use the measuring cups and spoons that the recipe was written for, because cup sizes differ from country to country. For tanks and pools, convert the volume and then add a safety margin. For medicine, chemicals or anything regulated, follow the label and a qualified person, because a rounded conversion is not precise enough for dosing.

Frequently asked questions

Are US gallons the same as imperial gallons?

No. The converter uses US gallons. Confirm the unit system before using a conversion.

Can I use this for medication doses?

Do not rely on a rounded general converter for medication dosing. Follow the product label and a qualified professional’s instructions.

How many US cups are in a litre?

One litre is about 4.23 US cups.

Is a US gallon the same as a UK gallon?

No. A US gallon is about 3.785 litres and a UK (imperial) gallon is about 4.546 litres. This tool uses the US gallon.
