Frequently Asked Questions

What units does the Volume Converter support?

The Volume Converter supports 12 units: milliliter (mL), liter (L), US gallon, UK gallon, quart, pint, cup, fluid ounce (fl oz), tablespoon (tbsp), teaspoon (tsp), cubic meter (m³), and cubic foot (ft³).

What is the difference between US and UK gallons?

A US gallon equals approximately 3.785 liters, while a UK (imperial) gallon equals approximately 4.546 liters. The UK gallon is about 20% larger than the US gallon, so it's important to select the correct one for your conversion.

How does the swap button work?

The swap button exchanges the source and target units, so you can quickly reverse the conversion direction. The result recalculates automatically after swapping, saving you from re-entering the value.

What is the Common Volume References table?

The Common Volume References table shows real-world volume comparisons — from a teaspoon to an Olympic swimming pool — with their equivalent values in liters, gallons, and milliliters. It helps you visualize and understand volume scales.

Can I copy individual conversion results?

Yes, each conversion result in the all-conversions grid has a copy button. Click it to copy the value with its unit label to your clipboard, which is handy for pasting into documents or spreadsheets.
