US Fluid Ounces to US Pints (fl oz to pt)
1 US fluid ounce equals 0.0625 US pints exactly.
How to convert US fluid ounces to US pints
To convert US fluid ounces to US pints, multiply the number of US fluid ounces by 0.0625. This factor is exact. To go the other way, multiply US pints by 16.
US pints = US fluid ounces × 0.0625
Example: 10 US fluid ounces = 0.625 US pints.
Pints, quarts, gallons and fluid ounces differ between the US and the UK. Units are labeled 'US' or 'imperial' to avoid confusion.
About these units
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).

US Pint (pt)
One eighth of a US gallon, 473.176 mL (16 US fluid ounces). The US pint is about 17% smaller than the imperial pint.
Pint seems to come from Old French pinte, possibly from a Latin word meaning painted, perhaps because capacity marks were painted on containers. British North America inherited the 231-cubic-inch wine gallon around 1707, and the US liquid pint was derived from it as one eighth. After Britain adopted the imperial gallon in 1824, American and British pints parted ways for good.
Today the US liquid pint is exactly 28.875 cubic inches, or 473.176473 milliliters. The imperial pint, at 568.26125 mL, is about 20 percent larger. That is why a pint of beer in an American bar is a lesser drink than a pint in an English pub, and why recipes from different countries cannot swap pints blindly. In the US a pint is a common size for ice cream, cream and craft beer, and a separate US dry pint of about 550.6 milliliters measures blueberries and cherry tomatoes.
1 US pint = 0.473176473 liters (exactly).
