Metrication in the United States fl oz, and 24 fl oz (355, 473, 591 and 710 mL) sizes. The half-liter water bottle (16.9 fl oz) has nearly replaced the 16 ounce size. 700 mL (23.6 fl oz) and one-liter sizes are also common, though 20 fl oz, and 24 fl oz sizes remain popular, particularly in vending machines. Attempts to sell 3- or 4-liter jugs of milk, instead of gallons (3.785 L), have been largely unsuccessful, and such bottles are rarely seen in the United States. Milk remains sold in binary divisions of the gallon, with half-pints, pints, quarts and half-gallons being the primary sizes.
