How to Convert Volume Units

Volume conversions are essential in the kitchen, at the fuel pump and in science class. American recipes use cups, tablespoons and fluid ounces, while the rest of the world measures in milliliters and liters. This converter uses exact US customary definitions, such as 1 US gallon = 3.785411784 liters and 1 US cup = 236.5882365 mL, so your recipes and calculations always come out right.
