In practice
Pounds-to-ounces is the simplest weight conversion in the imperial and US customary systems: 1 lb is exactly 16 oz, so you just multiply by 16. It shows up in butchery (a 1.5 lb steak is 24 oz), in UK and US baby weights quoted as pounds and ounces, and in shipping rates that switch units at the 1 lb mark. Remember this is weight: a pound of feathers and a pound of bricks both weigh 16 oz, but only liquids are measured in fluid ounces, which is a different unit entirely.
