How the calculation works
All volume conversions use a direct multiplier from the base unit (milliliters). Each unit has a fixed conversion factor: 1 liter = 1000 milliliters, 1 US gallon = 3785.41 milliliters, 1 US cup = 240 milliliters, 1 fluid ounce = 29.5735 milliliters. To convert, the calculator first translates your "from" value to milliliters by multiplying by its factor, then translates milliliters to the "to" unit by dividing by the target factor. For example, 2 liters to gallons: 2 × 1000 = 2000 milliliters, then 2000 ÷ 3785.41 ≈ 0.528 US gallons.
