About these units
US Dry Pint (dry pt)
One 64th of a US bushel (0.5506 L), larger than the liquid pint. Used for cherry tomatoes and berries.
Pint comes from Old French pinte, possibly traced to a word meaning painted, which would point to marks painted inside a container to show its capacity. In the British North American colonies two separate gallon systems ran side by side, one derived from the 231 cubic inch wine gallon for liquids and one from the corn gallon, an eighth of the Winchester bushel, for grain and produce.
The US dry pint belongs to the second system. It is one 64th of the US bushel, which is fixed at 2,150.42 cubic inches, so a dry pint is about 33.6 cubic inches, or roughly 550.6 millilitres (0.5506 L as used here). It is also half a dry quart and a sixteenth of a peck. Because the liquid pint is only about 473 millilitres, the dry pint is some 16 percent larger.
Today the unit survives mainly on packaging. Blueberries and similar small fruit in the United States and Canada are sold in containers labelled 1 US dry pint, with a bilingual label giving 551 millilitres. Britain dropped both older gallons in 1824, so the imperial pint is a different, larger measure again.
1 US dry pint = 0.5506104714 liters (approximately).

US Fluid Ounce (fl oz)
One 128th of a US gallon, 29.5735 mL. Not the same as the weight ounce, and about 4% larger than the imperial fluid ounce.
Fluid ounce began as an attempt to link volume to weight: the volume occupied by one ounce of some substance, such as wine in England or water in Scotland. Definitions varied by region and by liquid. When Britain defined its imperial gallon in 1824 as the space of ten pounds of water, the imperial fluid ounce came out so that an ounce of water weighs about one avoirdupois ounce. The US fluid ounce followed a different path and comes from the older wine gallon.
The US fluid ounce is exactly 1/128 of a US gallon, 29.5735295625 milliliters, about 4 percent bigger than the imperial one at 28.4130625 milliliters. American nutrition labels use yet another figure, treating one fluid ounce as 30 milliliters, a convenient rounding for serving sizes. The name is a trap, because a fluid ounce measures space while a weight ounce measures mass. A US fluid ounce of water weighs a bit more than an ounce of weight, while a fluid ounce of honey weighs considerably more.
1 US fluid ounce = 0.02957352956 liters (approximately).
