a pint is equal to 1/2 quart.
There are three different quarts in use in Britain and the United States, and hence there are three different pints.
1. The U. S. liquid pint, equal to exactly 28.875 cubic inches, 16 fluid ounces, or approximately 473.176 milliliters
2. The U. S. dry pint, equal to 33.600 cubic inches or approximately 550.611 milliliters
3.The British Imperial pint, equal to 20 British fluid ounces, 34.678 cubic inches or approximately 568.261 milliliters.
so it can either be 473 or 550 in the USA or 568 in the UK
