Volume Converter

Enter one volume and instantly convert it to litres, cubic metres, US gallons, Imperial gallons, and other common units.

Use a comma or period as the decimal separator; do not use thousands separators.

Good to know

The volume converter converts directly in your browser between metric cubic units, metric capacity units, imperial capacity units, and US liquid measures. All results are calculated via a common cubic-meter base, so values from different measurement systems stay consistent with each other.

Typical searches include liters to gallons, cubic meters to liters, and cups to milliliters. Calculation runs locally in the browser. The US gallon (231 in³) and the imperial gallon (4.54609 L) are defined differently; volume is also not the same as mass — converting to weight additionally requires the substance's density.

Typical use cases

Convert container, tank, and shipping volumes

Convert technical or logistics volume figures between cubic meters, liters, and gallons, for example for tanks, containers, or freight documents.

Correctly distinguish US and imperial gallons

Avoid costly mistakes in import, formulation, or tank specs by deliberately converting between the US gallon (3.785 L) and the imperial gallon (4.546 L) instead of treating them as equal.

Convert recipe quantities between measurement systems

Convert larger liquid quantities from US recipes into liters; for small kitchen measures like teaspoons or cups, the dedicated cooking and baking converter is better suited.

Tips for better results

Don't treat US and imperial gallons as equal

A US gallon equals 231 cubic inches, an imperial gallon 4.54609 liters — the two definitions differ by around 20%, which becomes noticeable at larger quantities.

Factor in density separately for weight

Volume cannot be converted directly into weight, since different substances have different densities — use the material's density or a density converter for that.

How it works

Step by step

  1. 1

    Enter value and source unit

    Enter the volume value and choose the source unit from one of the four groups.

  2. 2

    Choose the target unit

    Choose the target unit, even from a different group, for example from metric cubic units to US liquid measures.

  3. 3

    Copy the result or swap units

    Copy one result or all results at once, or swap the source and target unit for the next conversion.

Features

Four unit groups

Metric cubic units, metric capacity, imperial capacity, and US liquid measures are cleanly separated.

Local conversion

Calculation happens directly in the browser, without transmission to a server.

Consistent calculation base

All units are calculated via a common cubic-meter base with transparent definitions such as 1 L = 1 dm³.

Frequently asked questions

What is the difference between a US and an imperial gallon?

A US gallon equals 231 cubic inches (3.785 L), an imperial gallon 4.54609 liters — both systems are defined differently.

Can I convert volume directly into weight?

No. Volume is not the same as mass; that additionally requires the density of the substance in question.

Are my inputs uploaded?

No. Conversion runs entirely locally in the browser.
