In the United States, 1 pint is 16 fluid ounces which is equal to one pound (also 16 ounces). This only works for water however as it has a density of 1. For anything else this would be incorrect as a pint is a unit of volume and a pound is a unit of weight. In the rest of the English speaking world, an Imperial Pint (which is 20 Imperal Ounces) will weigh one and a quarter pounds. Note that a pint is 16 ounces of volume, while a pound is 16 ounces of mass. The popular rhyme A pint's a pound, the world around can help you remember this, but keep in mind that they're not really equivalent, and that this is not true the world around, but only in the U.S.
