Ounces = Stones × 224Stones to ounces multiplies by 224 exactly (14 lb × 16 oz). A 2 st toddler weighs 448 oz; half a stone is 112 oz. Both units sit on the avoirdupois ladder, so the factor is a clean integer with no rounding. The conversion is rare in practice — stones describe whole bodies, ounces describe portions — but it matters when a UK-stated birth or pet weight needs restating for a US form that expects pounds and ounces: 1 st 3 lb is 17 lb 0 oz, i.e. 272 oz total.
British market traders selling small goods by weight sometimes quote in ounces for precision while the customer thinks in stone-scale terms for reference — 1 st is 224 oz, 0.5 st is 112 oz, and 2 st is 448 oz. As the exact inverse of the ounce-to-stone pairing, 224 is the number worth remembering: any stone value multiplied by 224 gives an exact whole-ounce answer with no rounding involved.

The stone (st) equals exactly 14 pounds (about 6.35 kg). It is still widely used in the United Kingdom and Ireland to state body weight, even though it is no longer legal for trade. The stone was originally a real stone used by merchants as a counterweight on balances; its weight varied by region and trade until standardized in the late 19th century.
The avoirdupois ounce (oz) is a unit of mass in the imperial and US customary systems, defined as exactly 28.349523125 grams (1/16 of an avoirdupois pound). It is the standard small-mass unit in the United States for food packaging, recipes, and postal weights. Do not confuse it with the troy ounce (used for precious metals, 31.1035 g) or the fluid ounce (a volume).
