Formula

oz = lb × (0.45359237 / 0.028349523125)

A pound holds 16 ounces, so multiply pounds by 16. NIST Handbook 44 sets 16 avoirdupois ounces per pound, and the pound is 0.45359237 kg under NIST footnote 22. Birth weights, postal rates, and deli counters mix the two units, and 7.5 lb of flour is 120 oz. These ounces measure mass, so a troy ounce of gold or a fluid ounce of water needs a different calculation.
