Cooking, science and shipping all measure volume differently — and a US gallon is not a UK gallon. This converter covers 12+ volume units: liters, milliliters, US and UK gallons, cubic meters, cubic centimeters, pints, quarts, cups, fluid ounces, tablespoons and teaspoons, across metric and imperial systems. That range handles everything from scaling a recipe written in cups to working out tank capacity in cubic meters, with accurate standard factors behind every result (1 US gallon = 3.78541 liters; 1 UK gallon = 4.54609 liters).
Chefs use it to translate recipes, students and scientists for lab measurements, and businesses for liquid shipping and storage. It works on mobile and desktop with no login and no personal data required. Free, with no sign-up.
