How to use the volume converter
This volume converter lets you switch between common metric and US customary volume units in one place. Choose the unit you are converting from and the unit you want to convert to, enter a numeric value, and click "Convert" to see the result. A "Swap" button reverses the from and to units so you can check conversions in both directions without retyping. All conversions are based on the liter: every unit is defined relative to liters, so the tool stays consistent and accurate.
Volume conversion is useful in many situations. Cooks often need to convert between cups, fluid ounces, and milliliters when following recipes from different countries. Scientists and engineers work with liters, cubic meters, and cubic feet. Drivers in the US think in gallons; in most of the world, fuel is sold in liters. Whether you are scaling a recipe, comparing product sizes, or doing homework, having a single tool that handles liters, milliliters, US gallons, quarts, pints, cups, fluid ounces, cubic meters, and cubic feet saves time and reduces errors.
The converter runs entirely in your browser. There is no sign-up, no download, and no delay. It is designed to be mobile-friendly: the two-column layout stacks on small screens, inputs have a comfortable touch size, and the result appears next to your input so you can compare at a glance. Results are shown with up to six decimal places when needed, so you get both quick everyday conversions and precise values for technical use.
