Good to know
Decimal pounds from a scale: a deli or shipping scale that reads 2.3 lb means 2 lb plus 0.3 × 16 = 4.8 oz, not 2 lb 3 oz. Multiply only the decimal part by 16 to get the leftover ounces.
Recipes and portions: a quarter-pound burger is 4 oz, half a pound of cheese is 8 oz and a 1.5 lb loaf is 24 oz. US packaging often shows both, such as 'NET WT 24 OZ (1 LB 8 OZ)'.
Not fluid ounces: a pound of water is about 15.3 US fl oz, and a pound of flour fills roughly 3.6 cups. Gold and silver use troy weight, with 12 troy ounces to a troy pound.
