Actually, in the UK, a pint is 20 fluid oz, not 16. So when looking at UK recipes you have to take this into account. Much better to use grams and litres!

As they used to say, "A pint's a pound, the world around".

Google is your friend for this.

16 ounces = 1 pound = 1 pint.

Do you have the cookbook, "The Joy of Cooking?" It has a conversion table for all kinds of measurements toward the back - I've got a permanent bookmark there!

By weight, 16 ounces = 1 pound.
Ounces in liquid measure do not have a standard weight -- it's a volume measurements.
