How to convert volume units
The liter is the standard metric unit for liquid volume. One liter equals exactly 1,000 milliliters. The US gallon is defined as exactly 231 cubic inches, which equals approximately 3.785 liters.
An important distinction: the US gallon and the UK (imperial) gallon are different. A US gallon = 3.785 liters, while a UK gallon = 4.546 liters. Similarly, a US pint = 473 ml while a UK pint = 568 ml. Always check which system a recipe or specification uses.
For solid volumes, cubic meters, cubic feet, and cubic inches are used. One cubic foot = 28.317 liters = 7.481 US gallons — commonly needed for aquarium sizes, pool volumes, and construction calculations.
