Volume Converter is a free online tool that converts volume and capacity measurements between eleven units: milliliters, liters, cubic meters, US gallons, UK gallons, quarts, pints, cups, tablespoons, teaspoons, and fluid ounces. This tool is indispensable for cooking, science, engineering, and everyday tasks requiring conversion between metric and US customary volume measurements. The metric system uses liters as the practical unit for everyday volumes, with 1 liter equaling 1000 milliliters or 0.001 cubic meters. US customary units include gallons, quarts, pints, cups, and fluid ounces, all interrelated by factors of 2 or 4. Importantly, US gallons differ from UK (Imperial) gallons: a US gallon is 3.785 liters while a UK gallon is 4.546 liters, a difference of about 20 percent. This converter includes both US and UK gallon measurements to avoid confusion in international recipes and industrial specifications. Cooking measurements like cups, tablespoons, and teaspoons use US customary definitions. All calculations happen entirely in your browser with no data transmitted to any server.
