Before you rely on it
Weight ounces, not fluid ounces
This is the weight ounce: 1 pound is exactly 16 ounces. It is what a scale shows.
The fluid ounce measures liquid volume instead and is a different unit with the same nickname. For drinks and recipes with liquids, use the fluid ounce pages.
Package and baby weights are often written in pounds and ounces together — 2 lb 5 oz. Convert the pounds and add the ounces: 2 × 16 + 5 = 37 oz. Typing 2.5 means two and a half pounds, which is 40 oz, not 2 lb 5 oz.
The troy pound used for precious metals holds only 12 troy ounces, and a troy ounce is heavier than an ordinary one. This page uses the everyday avoirdupois pound and ounce, 16 to the pound.

Only for a known liquid, because a pound is a weight and a fluid ounce is a volume. For water, where 1 g fills about 1 mL, 1 lb is about 15.3 US fl oz. Oil is lighter and honey heavier, so the same pound fills a different number of fluid ounces.
